Police Detective Films

The police are a constituted body of persons empowered by a state, with the aim to enforce the law, to ensure the safety, health and possessions of citizens, and to prevent crime and civil disorder. Their lawful powers include arrest and the use of force legitimized by the state via the monopoly on violence. The term is most commonly associated with the police forces of a sovereign state that are authorized to exercise the police power of that state within a defined legal or territorial area of responsibility. Police forces are often defined as being separate from the military and other organizations involved in the defense of the state against foreign aggressors; however, gendarmerie are military units charged with civil policing. Police forces are usually public sector services, funded through taxes.

Law enforcement is only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Police forces have become ubiquitous in modern societies. Nevertheless, their role can be controversial, as they may be involved to varying degrees in corruption, brutality and the enforcement of authoritarian rule.

A police force may also be referred to as a police department, police service, constabulary, gendarmerie, crime prevention, protective services, law enforcement agency, civil guard, or civic guard. Members may be referred to as police officers, troopers, sheriffs, constables, rangers, peace officers or civic/civil guards. Ireland differs from other English-speaking countries by using the Irish language terms ''Garda'' (singular) and ''Gardaí'' (plural), for both the national police force and its members. The word ''police'' is the most universal and similar terms can be seen in many non-English speaking countries.

Numerous slang terms exist for the police. Many slang terms for police officers are decades or centuries old with lost etymologies. One of the oldest, ''cop'', has largely lost its slang connotations and become a common colloquial term used both by the public and police officers to refer to their profession.

Etymology

First attested in English in the early 15th century, originally in a range of senses encompassing '(public) policy; state; public order', the word ''police'' comes from Middle French ('public order, administration, government'), in turn from Latin , which is the romanization of the Ancient Greek () 'citizenship, administration, civil polity'. This is derived from () 'city'.

History

Ancient

China

Law enforcement in ancient China was carried out by "prefects" for thousands of years since it developed in both the Chu and Jin kingdoms of the Spring and Autumn period. In Jin, dozens of prefects were spread across the state, each having limited authority and employment period. They were appointed by local magistrates, who reported to higher authorities such as governors, who in turn were appointed by the emperor, and they oversaw the civil administration of their "prefecture", or jurisdiction. Under each prefect were "subprefects" who helped collectively with law enforcement in the area. Some prefects were responsible for handling investigations, much like modern police detectives. Prefects could also be women. Local citizens could report minor judicial offenses against them such as robberies at a local prefectural office. The concept of the "prefecture system" spread to other cultures such as Korea and Japan.

Babylonia

In Babylonia, law enforcement tasks were initially entrusted to individuals with military backgrounds or imperial magnates during the Old Babylonian period, but eventually, law enforcement was delegated to officers known as , who were present in both cities and rural settlements. A was responsible for investigating petty crimes and carrying out arrests.

Egypt

In ancient Egypt evidence of law enforcement exists as far back as the Old Kingdom period. There are records of an office known as "Judge Commandant of the Police" dating to the fourth dynasty. During the fifth dynasty at the end of the Old Kingdom period, officers armed with wooden sticks were tasked with guarding public places such as markets, temples, and parks, and apprehending criminals. They are known to have made use of trained monkeys, baboons, and dogs in guard duties and catching criminals. After the Old Kingdom collapsed, ushering in the First Intermediate Period, it is thought that the same model applied. During this period, Bedouins were hired to guard the borders and protect trade caravans. During the Middle Kingdom period, a professional police force was created with a specific focus on enforcing the law, as opposed to the previous informal arrangement of using warriors as police. The police force was further reformed during the New Kingdom period. Police officers served as interrogators, prosecutors, and court bailiffs, and were responsible for administering punishments handed down by judges. In addition, there were special units of police officers trained as priests who were responsible for guarding temples and tombs and preventing inappropriate behavior at festivals or improper observation of religious rites during services. Other police units were tasked with guarding caravans, guarding border crossings, protecting royal necropolises, guarding slaves at work or during transport, patrolling the Nile River, and guarding administrative buildings. By the Eighteenth Dynasty of the New Kingdom period, an elite desert-ranger police force called the Medjay was used to protect valuable areas, especially areas of pharaonic interest like capital cities, royal cemeteries, and the borders of Egypt. Though they are best known for their protection of the royal palaces and tombs in Thebes and the surrounding areas, the Medjay were used throughout Upper and Lower Egypt. Each regional unit had its own captain. The police forces of ancient Egypt did not guard rural communities, which often took care of their own judicial problems by appealing to village elders, but many of them had a constable to enforce state laws.

Greece

In ancient Greece, publicly owned slaves were used by magistrates as police. In Athens, the Scythian Archers (the 'rod-bearers'), a group of about 300 Scythian slaves, was used to guard public meetings to keep order and for crowd control, and also assisted with dealing with criminals, handling prisoners, and making arrests. Other duties associated with modern policing, such as investigating crimes, were left to the citizens themselves. Athenian police forces were supervised by the Areopagus. In Sparta, the Ephors were in charge of maintaining public order as judges, and they used Sparta's Hippeis, a 300-member royal guard of honor, as their enforcers. There were separate authorities supervising women, children, and agricultural issues. Sparta also had a secret police force called the crypteia to watch the large population of helots, or slaves.

Rome

In the Roman Empire, the army played a major role in providing security. Roman soldiers detached from their legions and posted among civilians carried out law enforcement tasks. Local watchmen were hired by cities to provide some extra security. Magistrates such as ''tresviri capitales'', and investigated crimes. There was no concept of public prosecution, so victims of crime or their families had to organize and manage the prosecution themselves. Under the reign of Augustus, when the capital had grown to almost one million inhabitants, 14 wards were created; the wards were protected by seven squads of 1,000 men called , who acted as night watchmen and firemen. Their duties included apprehending petty criminals, capturing runaway slaves, guarding the baths at night, and stopping disturbances of the peace. The primarily dealt with petty crime, while violent crime, sedition, and rioting was handled by the Urban Cohorts and even the Praetorian Guard if necessary, though the vigiles could act in a supporting role in these situations.

India

Law enforcement systems existed in the various kingdoms and empires of ancient India. The Apastamba Dharmasutra prescribes that kings should appoint officers and subordinates in the towns and villages to protect their subjects from crime. Various inscriptions and literature from ancient India suggest that a variety of roles existed for law enforcement officials such as those of a constable, thief catcher, watchman, and detective. In ancient India up to medieval and early modern times, kotwals were in charge of local law enforcement.

Persian Empire

The Persian Empire had well-organized police forces. A police force existed in every place of importance. In the cities, each ward was under the command of a Superintendent of Police, known as a , who was expected to command implicit obedience in his subordinates. Police officers also acted as prosecutors and carried out punishments imposed by the courts. They were required to know the court procedure for prosecuting cases and advancing accusations.

Israel

In ancient Israel and Judah, officials with the responsibility of making declarations to the people, guarding the king's person, supervising public works, and executing the orders of the courts existed in the urban areas. They are repeatedly mentioned in the Hebrew Bible, and this system lasted into the period of Roman rule. The first century Jewish historian Josephus related that every judge had two such officers under his command. Levites were preferred for this role. Cities and towns also had night watchmen. Besides officers of the town, there were officers for every tribe. The temple in Jerusalem had special temple police to guard it. The Talmud mentions various local police officials in the Jewish communities of the Land of Israel and Babylon who supervised economic activity. Their Greek-sounding titles suggest that the roles were introduced under Hellenic influence. Most of these officials received their authority from local courts and their salaries were drawn from the town treasury. The Talmud also mentions city watchmen and mounted and armed watchmen in the suburbs.

Africa

In many regions of pre-colonial Africa, particularly West and Central Africa, guild-like secret societies emerged as law enforcement. In the absence of a court system or written legal code, they carried out police-like activities, employing varying degrees of coercion to enforce conformity and deter antisocial behavior. In ancient Ethiopia, armed retainers of the nobility enforced law in the countryside according to the will of their leaders. The Songhai Empire had officials known as ''assara-munidios'', or "enforcers", acting as police.

The Americas

Pre-Columbian civilizations in the Americas also had organized law enforcement. The city-states of the Maya civilization had constables known as , as well as bailiffs. In the Aztec Empire, judges had officers serving under them who were empowered to perform arrests, even of dignitaries. In the Inca Empire, officials called enforced the law among the households they were assigned to oversee, with inspectors known as () also stationed throughout the provinces to keep order.

Post-classical

In medieval Spain, , or 'holy brotherhoods', peacekeeping associations of armed individuals, were a characteristic of municipal life, especially in Castile. As medieval Spanish kings often could not offer adequate protection, protective municipal leagues began to emerge in the twelfth century against banditry and other rural criminals, and against the lawless nobility or to support one or another claimant to a crown.

These organizations were intended to be temporary, but became a long-standing fixture of Spain. The first recorded case of the formation of an occurred when the towns and the peasantry of the north united to police the pilgrim road to Santiago de Compostela in Galicia, and protect the pilgrims against robber knights.

Throughout the Middle Ages such alliances were frequently formed by combinations of towns to protect the roads connecting them, and were occasionally extended to political purposes. Among the most powerful was the league of North Castilian and Basque ports, the Hermandad de las marismas: Toledo, Talavera, and Villarreal.

As one of their first acts after end of the War of the Castilian Succession in 1479, Ferdinand II of Aragon and Isabella I of Castile established the centrally-organized and efficient ''Holy Brotherhood'' as a national police force. They adapted an existing brotherhood to the purpose of a general police acting under officials appointed by themselves, and endowed with great powers of summary jurisdiction even in capital cases. The original brotherhoods continued to serve as modest local police-units until their final suppression in 1835.

The Vehmic courts of Germany provided some policing in the absence of strong state institutions. Such courts had a chairman who presided over a session and lay judges who passed judgement and carried out law enforcement tasks. Among the responsibilities that lay judges had were giving formal warnings to known troublemakers, issuing warrants, and carrying out executions.

In the medieval Islamic Caliphates, police were known as . Bodies termed existed perhaps as early as the Caliphate of Uthman. The Shurta is known to have existed in the Abbasid and Umayyad Caliphates. Their primary roles were to act as police and internal security forces but they could also be used for other duties such as customs and tax enforcement, rubbish collection, and acting as bodyguards for governors. From the 10th century, the importance of the Shurta declined as the army assumed internal security tasks while cities became more autonomous and handled their own policing needs locally, such as by hiring watchmen. In addition, officials called were responsible for supervising bazaars and economic activity in general in the medieval Islamic world.

In France during the Middle Ages, there were two Great Officers of the Crown of France with police responsibilities: The Marshal of France and the Grand Constable of France. The military policing responsibilities of the Marshal of France were delegated to the Marshal's provost, whose force was known as the Marshalcy because its authority ultimately derived from the Marshal. The marshalcy dates back to the Hundred Years' War, and some historians trace it back to the early 12th century. Another organisation, the Constabulary ( fro, Connétablie), was under the command of the Constable of France. The constabulary was regularised as a military body in 1337. Under Francis I (reigned 1515–1547), the was merged with the constabulary. The resulting force was also known as the , or, formally, the Constabulary and Marshalcy of France.

The English system of maintaining public order since the Norman conquest was a private system of tithings known as the mutual pledge system. This system was introduced under Alfred the Great. Communities were divided into groups of ten families called tithings, each of which was overseen by a chief tithingman. Every household head was responsible for the good behavior of his own family and the good behavior of other members of his tithing. Every male aged 12 and over was required to participate in a tithing. Members of tithings were responsible for raising "hue and cry" upon witnessing or learning of a crime, and the men of his tithing were responsible for capturing the criminal. The person the tithing captured would then be brought before the chief tithingman, who would determine guilt or innocence and punishment. All members of the criminal's tithing would be responsible for paying the fine. A group of ten tithings was known as a "hundred" and every hundred was overseen by an official known as a reeve. Hundreds ensured that if a criminal escaped to a neighboring village, he could be captured and returned to his village. If a criminal was not apprehended, then the entire hundred could be fined. The hundreds were governed by administrative divisions known as shires, the rough equivalent of a modern county, which were overseen by an official known as a shire-reeve, from which the term sheriff evolved. The shire-reeve had the power of , meaning he could gather the men of his shire to pursue a criminal. Following the Norman conquest of England in 1066, the tithing system was tightened with the frankpledge system. By the end of the 13th century, the office of constable developed. Constables had the same responsibilities as chief tithingmen and additionally as royal officers. The constable was elected by his parish every year. Eventually, constables became the first 'police' official to be tax-supported. In urban areas, watchmen were tasked with keeping order and enforcing nighttime curfew. Watchmen guarded the town gates at night, patrolled the streets, arrested those on the streets at night without good reason, and also acted as firefighters. Eventually the office of justice of the peace was established, with a justice of the peace overseeing constables. There was also a system of investigative "juries".

The Assize of Arms of 1252, which required the appointment of constables to summon men to arms, quell breaches of the peace, and to deliver offenders to the sheriff or reeve, is cited as one of the earliest antecedents of the English police. The Statute of Winchester of 1285 is also cited as the primary legislation regulating the policing of the country between the Norman Conquest and the Metropolitan Police Act 1829.

From about 1500, private watchmen were funded by private individuals and organisations to carry out police functions. They were later nicknamed 'Charlies', probably after the reigning monarch King Charles II. Thief-takers were also rewarded for catching thieves and returning the stolen property. They were private individuals usually hired by crime victims.

The earliest English use of the word ''police'' seems to have been the term ''Polles'' mentioned in the book ''The Second Part of the Institutes of the Lawes of England'' published in 1642.

Early modern

The first centrally organised and uniformed police force was created by the government of King Louis XIV in 1667 to police the city of Paris, then the largest city in Europe. The royal edict, registered by the of Paris on March 15, 1667, created the office of ("lieutenant general of police"), who was to be the head of the new Paris police force, and defined the task of the police as "ensuring the peace and quiet of the public and of private individuals, purging the city of what may cause disturbances, procuring abundance, and having each and everyone live according to their station and their duties".

This office was first held by Gabriel Nicolas de la Reynie, who had 44 ('police commissioners') under his authority. In 1709, these commissioners were assisted by ('police inspectors'). The city of Paris was divided into 16 districts policed by the , each assigned to a particular district and assisted by a growing bureaucracy. The scheme of the Paris police force was extended to the rest of France by a royal edict of October 1699, resulting in the creation of lieutenants general of police in all large French cities and towns.

After the French Revolution, Napoléon I reorganized the police in Paris and other cities with more than 5,000 inhabitants on February 17, 1800, as the Prefecture of Police. On March 12, 1829, a government decree created the first uniformed police in France, known as ('city sergeants'), which the Paris Prefecture of Police's website claims were the first uniformed policemen in the world.

In feudal Japan, samurai warriors were charged with enforcing the law among commoners. Some Samurai acted as magistrates called , who acted as judges, prosecutors, and as chief of police. Beneath them were other Samurai serving as , or assistant magistrates, who conducted criminal investigations, and beneath them were Samurai serving as , who were responsible for patrolling the streets, keeping the peace, and making arrests when necessary. The were responsible for managing the . and were typically drawn from low-ranking samurai families. This system typically did not apply to the Samurai themselves. Samurai clans were expected to resolve disputes among each other through negotiation, or when that failed through duels. Only rarely did Samurai bring their disputes to a magistrate or answer to police. Assisting the were the , non-Samurai who went on patrol with them and provided assistance, the , non-Samurai from the lowest outcast class, often former criminals, who worked for them as informers and spies, and or , chōnin, often former criminals, who were hired by local residents and merchants to work as police assistants in a particular neighborhood.

In Sweden, local governments were responsible for law and order by way of a royal decree issued by Magnus III in the 13th century. The cities financed and organized groups of watchmen who patrolled the streets. In the late 1500s in Stockholm, patrol duties were in large part taken over by a special corps of salaried city guards. The city guard was organized, uniformed and armed like a military unit and was responsible for interventions against various crimes and the arrest of suspected criminals. These guards were assisted by the military, fire patrolmen, and a civilian unit that did not wear a uniform, but instead wore a small badge around the neck. The civilian unit monitored compliance with city ordinances relating to e.g. sanitation issues, traffic and taxes. In rural areas, the King's bailiffs were responsible for law and order until the establishment of counties in the 1630s.

Up to the early 18th century, the level of state involvement in law enforcement in Britain was low. Although some law enforcement officials existed in the form of constables and watchmen, there was no organized police force. A professional police force like the one already present in France would have been ill-suited to Britain, which saw examples such as the French one as a threat to the people's liberty and balanced constitution in favor of an arbitrary and tyrannical government. Law enforcement was mostly up to the private citizens, who had the right and duty to prosecute crimes in which they were involved or in which they were not. At the cry of 'murder!' or 'stop thief!' everyone was entitled and obliged to join the pursuit. Once the criminal had been apprehended, the parish constables and night watchmen, who were the only public figures provided by the state and who were typically part-time and local, would make the arrest. As a result, the state set a reward to encourage citizens to arrest and prosecute offenders. The first of such rewards was established in 1692 of the amount of £40 for the conviction of a highwayman and in the following years it was extended to burglars, coiners and other forms of offense. The reward was to be increased in 1720 when, after the end of the War of the Spanish Succession and the consequent rise of criminal offenses, the government offered £100 for the conviction of a highwayman. Although the offer of such a reward was conceived as an incentive for the victims of an offense to proceed to the prosecution and to bring criminals to justice, the efforts of the government also increased the number of private thief-takers. Thief-takers became infamously known not so much for what they were supposed to do, catching real criminals and prosecuting them, as for "setting themselves up as intermediaries between victims and their attackers, extracting payments for the return of stolen goods and using the threat of prosecution to keep offenders in thrall". Some of them, such as Jonathan Wild, became infamous at the time for staging robberies in order to receive the reward.

In 1737, George II began paying some London and Middlesex watchmen with tax monies, beginning the shift to government control. In 1749, Judge Henry Fielding began organizing a force of quasi-professional constables known as the Bow Street Runners. The Bow Street Runners are considered to have been Britain's first dedicated police force. They represented a formalization and regularization of existing policing methods, similar to the unofficial 'thief-takers'. What made them different was their formal attachment to the Bow Street magistrates' office, and payment by the magistrate with funds from the central government. They worked out of Fielding's office and court at No. 4 Bow Street, and did not patrol but served writs and arrested offenders on the authority of the magistrates, travelling nationwide to apprehend criminals. Fielding wanted to regulate and legalize law enforcement activities due to the high rate of corruption and mistaken or malicious arrests seen with the system that depended mainly on private citizens and state rewards for law enforcement. Henry Fielding's work was carried on by his brother, Justice John Fielding, who succeeded him as magistrate in the Bow Street office. Under John Fielding, the institution of the Bow Street Runners gained more and more recognition from the government, although the force was only funded intermittently in the years that followed. In 1763, the Bow Street Horse Patrol was established to combat highway robbery, funded by a government grant. The Bow Street Runners served as the guiding principle for the way that policing developed over the next 80 years. Bow Street was a manifestation of the move towards increasing professionalisation and state control of street life, beginning in London.

The Macdaniel affair, a 1754 British political scandal in which a group of thief-takers was found to be falsely prosecuting innocent men in order to collect reward money from bounties, added further impetus for a publicly salaried police force that did not depend on rewards. Nonetheless, In 1828, there were privately financed police units in no fewer than 45 parishes within a 10-mile radius of London.

The word ''police'' was borrowed from French into the English language in the 18th century, but for a long time it applied only to French and continental European police forces. The word, and the concept of police itself, were "disliked as a symbol of foreign oppression". Before the 19th century, the first use of the word ''police'' recorded in government documents in the United Kingdom was the appointment of Commissioners of Police for Scotland in 1714 and the creation of the Marine Police in 1798.

Modern

Scotland and Ireland

Following early police forces established in 1779 and 1788 in Glasgow, Scotland, the Glasgow authorities successfully petitioned the government to pass the Glasgow Police Act establishing the City of Glasgow Police in 1800. Other Scottish towns soon followed suit and set up their own police forces through acts of parliament. In Ireland, the Irish Constabulary Act of 1822 marked the beginning of the Royal Irish Constabulary. The Act established a force in each barony with chief constables and inspectors general under the control of the civil administration at Dublin Castle. By 1841 this force numbered over 8,600 men.

London

In 1797, Patrick Colquhoun was able to persuade the West Indies merchants who operated at the Pool of London on the River Thames to establish a police force at the docks to prevent rampant theft that was causing annual estimated losses of £500,000 worth of cargo.Dick Paterson
Origins of the Thames Police
, ''Thames Police Museum''. Retrieved 4 February 2007. The idea of a police, as it then existed in France, was considered as a potentially undesirable foreign import. In building the case for the police in the face of England's firm anti-police sentiment, Colquhoun framed the political rationale on economic indicators to show that a police dedicated to crime prevention was "perfectly congenial to the principle of the British constitution". Moreover, he went so far as to praise the French system, which had reached "the greatest degree of perfection" in his estimation.T.A. Critchley, ''A History of Police in England and Wales'', 2nd edition. Montclair, NJ: Patterson Smith, 38–39.

With the initial investment of £4,200, the new force the Thames River Police#Marine Police, Marine Police began with about 50 men charged with policing 33,000 workers in the river trades, of whom Colquhoun claimed 11,000 were known criminals and "on the game". The force was part funded by the London Society of West India Planters and Merchants. The force was a success after its first year, and his men had "established their worth by saving £122,000 worth of cargo and by the rescuing of several lives". Word of this success spread quickly, and the government passed the Depredations on the Thames Act 1800 on 28 July 1800, establishing a fully funded police force the Thames River Police together with new laws including police powers; now the oldest police force in the world. Colquhoun published a book on the experiment, ''The Commerce and Policing of the River Thames''. It found receptive audiences far outside London, and inspired similar forces in other cities, notably, New York City, Dublin, and Sydney.

Colquhoun's utilitarian approach to the problem – using a cost-benefit analysis, cost-benefit argument to obtain support from businesses standing to benefit – allowed him to achieve what Henry Fielding, Henry and John Fielding failed for their Bow Street detectives. Unlike the stipendiary system at Bow Street, the river police were full-time, salaried officers prohibited from taking private fees. His other contribution was the concept of preventive policing; his police were to act as a highly visible deterrent to crime by their permanent presence on the Thames. Colquhoun's innovations were a critical development leading up to Robert Peel's "new" police three decades later.

Metropolitan

London was fast reaching a size unprecedented in world history, due to the onset of the Industrial Revolution. It became clear that the locally maintained system of volunteer constables and "watchmen" was ineffective, both in detecting and preventing crime. A parliamentary committee was appointed to investigate the system of policing in London. Upon Robert Peel, Sir Robert Peel being appointed as Home Secretary in 1822, he established a second and more effective committee, and acted upon its findings.

Royal assent to the Metropolitan Police Act 1829 was given and the Metropolitan Police Service was established on September 29, 1829, in London. Peel, widely regarded as the father of modern policing, was heavily influenced by the social and legal philosophy of Jeremy Bentham, who called for a strong and centralised, but politically neutral, police force for the maintenance of social order, for the protection of people from crime and to act as a visible Preventive police, deterrent to urban crime and disorder. Peel decided to standardise the police force as an official paid profession, to organise it in a civilian fashion, and to make it answerable to the public.

Due to public fears concerning the deployment of the military in domestic matters, Peel organised the force along civilian lines, rather than paramilitary. To appear neutral, the uniform was deliberately manufactured in blue, rather than red which was then a military colour, along with the officers being armed only with a wooden Baton (law enforcement), truncheon and a Ratchet (instrument), rattle to signal the need for assistance. Along with this, Police ranks of the United Kingdom, police ranks did not include military titles, with the exception of Sergeant#Police 7, Sergeant.

To distance the new police force from the initial public view of it as a new tool of government repression, Peel publicised the so-called Peelian principles, which set down basic guidelines for ethical policing:
* Whether the police are effective is not measured on the number of arrests but on the deterrence of crime.
* Above all else, an effective authority figure knows trust and accountability are paramount. Hence, Peel's most often quoted principle that "The police are the public and the public are the police."

The 1829 Metropolitan Police Act created a modern police force by limiting the purview of the force and its powers, and envisioning it as merely an organ of the judicial system. Their job was apolitical; to maintain the peace and apprehend criminals for the courts to process according to the law. This was very different from the "Continental Europe, continental model" of the police force that had been developed in France, where the police force worked within the parameters of the absolute monarchy, absolutist state as an extension of the authority of the monarch and functioned as part of the governing state.

In 1863, the Metropolitan Police were issued with the distinctive custodian helmet, and in 1884 they switched to the use of whistles that could be heard from much further away. The Metropolitan Police became a model for the police forces in many countries, including the United States and most of the British Empire. Bobbies can still be found in many parts of the Commonwealth of Nations.

Australia

In Australia, organized law enforcement emerged soon after British colonization began in 1788. The first law enforcement organizations were the Night Watch and Row Boat Guard, which were formed in 1789 to police Sydney. Their ranks were drawn from well-behaved convicts deported to Australia. The Night Watch was replaced by the Sydney Foot Police in 1790. In New South Wales, rural law enforcement officials were appointed by local Justice of the peace, justices of the peace during the early to mid 19th century, and were referred to as "bench police" or "benchers". A mounted police force was formed in 1825.

The first police force having centralised command as well as jurisdiction over an entire colony was the South Australia Police, formed in 1838 under Henry Inman (police commander), Henry Inman. However, whilst the New South Wales Police Force was established in 1862, it was made up from a large number of policing and military units operating within the then Colony of New South Wales and traces its links back to the Royal Marines. The passing of the Police Regulation Act of 1862 essentially tightly regulated and centralised all of the police forces operating throughout the Colony of New South Wales.

Each Australian state and territory maintains its own police force, while the Australian Federal Police enforces laws at the federal level. The New South Wales Police Force remains the largest police force in Australia in terms of personnel and physical resources. It is also the only police force that requires its recruits to undertake university studies at the recruit level and has the recruit pay for their own education.

Brazil

In 1566, the first police investigator of Rio de Janeiro was recruited. By the 17th century, most captaincy, captaincies already had local units with law enforcement functions. On July 9, 1775, a Minas Gerais Military Police, Cavalry Regiment was created in the state of Minas Gerais for maintaining law and order. In 1808, the Portuguese royal family relocated to Brazil, because of the French invasion of Portugal. Dom João VI, King João VI established the ('General Police Intendancy') for investigations. He also created a Military Police of Rio de Janeiro State, Royal Police Guard for Rio de Janeiro in 1809. In 1831, after independence, each province started organizing its local "Military Police (Brazil), military police", with order maintenance tasks. The Federal Railroad Police was created in 1852, Federal Highway Police (Brazil), Federal Highway Police, was established in 1928, and Federal Police of Brazil, Federal Police in 1967.

Canada

During the early days of English and French colonization, municipalities hired watchmen and constables to provide security. Established in 1729, the Royal Newfoundland Constabulary (RNC) was the first policing service founded in Canada. The establishment of modern policing services in the Canadas occurred during the 1830s, modelling their services after the London Metropolitan Police, and adopting the ideas of the Peelian principles. The Toronto Police Service was established in 1834, whereas the Service de police de la Ville de Québec was established in 1840.

A national police service, the Dominion Police, was founded in 1868. Initially the Dominion Police provided security for parliament, but its responsibilities quickly grew. In 1870, Rupert's Land and the North-Western Territory were incorporated into the country. In an effort to police its newly acquired territory, the Canadian government established the North-West Mounted Police in 1873 (renamed Royal North-West Mounted Police in 1904). In 1920, the Dominion Police, and the Royal Northwest Mounted Police were amalgamated into the Royal Canadian Mounted Police (RCMP).

The RCMP provides federal law enforcement; and law enforcement in eight provinces, and all three territories. The provinces of Ontario, and Quebec maintain their own provincial police forces, the Ontario Provincial Police (OPP), and the Sûreté du Québec (SQ). Policing in Newfoundland and Labrador is provided by the RCMP, and the RNC. The aforementioned services also provides municipal policing, although larger Canadian municipalities may establish their own police service.

Lebanon

In Lebanon, the current police force were established in 1861, with creation of the Gendarmerie.

India

In India, the police are under the control of respective States and union territories of India, States and union territories and is known to be under State Police Services (India), State Police Services (SPS). The candidates selected for the SPS are usually posted as Deputy Superintendent of Police or Assistant Commissioner of Police once their probationary period ends. On prescribed satisfactory service in the SPS, the officers are nominated to the Indian Police Service. The service color is usually dark blue and red, while the uniform color is ''Khaki''.

United States

In Colonial history of the United States, Colonial America, the county sheriff was the most important law enforcement official. For instance, the New York Sheriff's Office was founded in 1626, and the Albany County Sheriff's Department (New York), Albany County Sheriff's Department in the 1660s. The county sheriff, who was an elected official, was responsible for enforcing laws, collecting taxes, supervising elections, and handling the legal business of the county government. Sheriffs would investigate crimes and make arrests after citizens filed complaints or provided information about a crime, but did not carry out patrols or otherwise take preventive action. Villages and cities typically hired constables and marshals, who were empowered to make arrests and serve warrants. Many municipalities also formed a night watch, or group of citizen volunteers who would patrol the streets at night looking for crime or fires. Typically, constables and marshals were the main law enforcement officials available during the day while the night watch would serve during the night. Eventually, municipalities formed day watch groups. Rioting was handled by local militias.

In the 1700s, the Province of Carolina (later North Carolina, North- and South Carolina) established slave patrols in order to prevent slave rebellions and enslaved people from escaping. By 1785 the Charleston, South Carolina, Charleston Guard and Watch had "a distinct command hierarchy, chain of command, uniforms, sole responsibility for policing, salary, authorized use of force, and a focus on crime prevention, preventing crime."

In 1789 the United States Marshals Service was established, followed by other federal services such as the United States Park Police, U.S. Parks Police (1791) and United States Mint Police, U.S. Mint Police (1792). The first city police services were established in Philadelphia Police Department, Philadelphia in 1751, Richmond, Virginia in 1807, Boston in 1838, and New York City, New York in 1845. The U.S. Secret Service was founded in 1865 and was for some time the main investigative body for the federal government.

In the American Old West, law enforcement was carried out by local sheriffs, rangers, constables, and federal marshals. There were also town marshals responsible for serving civil and criminal warrants, maintaining the jails, and carrying out arrests for petty crime.

In recent years, in addition to federal, state, and local forces, some Special district (United States), special districts have been formed to provide extra police protection in designated areas. These districts may be known as neighborhood improvement districts, crime prevention districts, or security districts.

In 2022, San Francisco supervisors approved allowing local police to use robots, and stipulates that can "be used as a deadly force option." This policy has been criticized by groups such as the Electronic Frontier Foundation and the ACLU stipulating that "killer robots will not make San Francisco better" and "police might even bring armed robots to a protest."

Development of theory

Michel Foucault wrote that the contemporary concept of police as a paid and funded functionary of the state was developed by German and French legal scholars and practitioners in public administration and statistics in the 17th and early 18th centuries, most notably with Nicolas Delamare's
Traité de la Police
' ("Treatise on the Police"), first published in 1705. The German ''Polizeiwissenschaft'' (Science of Police) first theorized by Philipp von Hörnigk, a 17th-century Austrian political economist and civil servant, and much more famously by Johann Heinrich Gottlob Justi, who produced an important theoretical work known as Cameral science on the formulation of police. Foucault cites Magdalene Humpert author of ''Bibliographie der Kameralwissenschaften'' (1937) in which the author makes note of a substantial bibliography was produced of over 4,000 pieces of the practice of ''Polizeiwissenschaft''. However, this may be a mistranslation of Foucault's own work since the actual source of Magdalene Humpert states over 14,000 items were produced from the 16th century dates ranging from 1520 to 1850.

As conceptualized by the ''Polizeiwissenschaft'', according to Foucault the police had an administrative, economic and social duty ("procuring abundance"). It was in charge of demographics, demographic concerns and needed to be incorporated within the western political philosophy system of raison d'état and therefore giving the superficial appearance of empowering the population (and unwittingly supervising the population), which, according to mercantilist theory, was to be the main strength of the state. Thus, its functions largely overreached simple law enforcement activities and included public health concerns, urban planning (which was important because of the miasma theory of disease; thus, cemeteries were moved out of town, etc.), and surveillance of prices.

The concept of preventive policing, or policing to deter crime from taking place, gained influence in the late 18th century. Police Magistrate John Fielding, head of the Bow Street Runners, argued that "...it is much better to prevent even one man from being a rogue than apprehending and bringing forty to justice."R.J. Marin, "The Living Law." In eds., W.T. McGrath and M.P. Mitchell, ''The Police Function in Canada''. Toronto: Methuen, 1981, 18–19.

The Utilitarianism, Utilitarian philosopher, Jeremy Bentham, promoted the views of Italy, Italian Cesare, Marquis of Beccaria, Marquis Cesare Beccaria, and disseminated a translated version of "Essay on Crime in Punishment". Bentham espoused the guiding principle of "the greatest good for the greatest number":

It is better to prevent crimes than to punish them. This is the chief aim of every good system of legislation, which is the art of leading men to the greatest possible happiness or to the least possible misery, according to calculation of all the goods and evils of life.

Patrick Colquhoun's influential work, ''A Treatise on the Police of the Metropolis'' (1797) was heavily influenced by Benthamite thought. Colquhoun's Marine Police Force, Thames River Police was founded on these principles, and in contrast to the Bow Street Runners, acted as a deterrent by their continual presence on the riverfront, in addition to being able to intervene if they spotted a crime in progress.

Edwin Chadwick's 1829 article, "Preventive police" in the ''London Review'', argued that prevention ought to be the ''primary'' concern of a police body, which was not the case in practice. The reason, argued Chadwick, was that "A preventive police would act more immediately by placing difficulties in obtaining the objects of temptation." In contrast to a deterrent of punishment, a preventive police force would deter criminality by making crime cost-ineffective – "crime doesn't pay". In the second draft of his 1829 Police Act, the "object" of the new Metropolitan Police, was changed by Robert Peel to the "principal object," which was the "prevention of crime." Later historians would attribute the perception of England's "appearance of orderliness and love of public order" to the preventive principle entrenched in Peel's police system.

Development of modern police forces around the world was contemporary to the formation of the state, later defined by sociologist Max Weber as achieving a "monopoly on the legitimate use of physical force" and which was primarily exercised by the police and the military. Marxist theory situates the development of the modern state as part of the rise of capitalism, in which the police are one component of the bourgeoisie's repressive apparatus for subjugating the working class. By contrast, the Peelian principles argue that "the power of the police...is dependent on public approval of their existence, actions and behavior", a philosophy known as policing by consent.

Personnel and organization

Police forces include both preventive (uniformed) police and detectives. Terminology varies from country to country. Police functions include protecting life and property, enforcing criminal law, criminal investigations, regulating traffic, crowd control, public safety duties, civil defense, emergency management, searching for missing persons, lost property and other duties concerned with public order. Regardless of size, police forces are generally organized as a hierarchy with multiple Police rank, ranks. The exact structures and the names of rank vary considerably by country.

Uniformed

The police who wear uniforms make up the majority of a police service's personnel. Their main duty is to respond to calls to the emergency telephone number. When not responding to these call-outs, they will do work aimed at preventing crime, such as patrols. The uniformed police are known by varying names such as preventive police, the uniform branch/division, administrative police, order police, the patrol bureau/division or patrol. In Australia and the United Kingdom, patrol personnel are also known as "general duties" officers. Atypically, Brazil's preventive police are known as Military Police (Brazil), Military Police.

As implied by the name, uniformed police wear uniforms. They perform functions that require an immediate recognition of an officer's legal authority and a potential need for force. Most commonly this means intervening to stop a crime in progress and securing the scene of a crime that has already happened. Besides dealing with crime, these officers may also manage and monitor traffic, carry out community policing duties, maintain order at public events or carry out searches for Missing person, missing people (in 2012, the latter accounted for 14% of police time in the United Kingdom). As most of these duties must be available as a 24/7 service, uniformed police are required to do shift work.

Detectives

Police detectives are responsible for investigations and detective work. Detectives may be called Investigations Police, Judiciary/Judicial Police, and Criminal Police. In the UK, they are often referred to by the name of their department, the Criminal Investigation Department, Criminal Investigation Department (CID). Detectives typically make up roughly 15–25% of a police service's personnel.

Detectives, in contrast to uniformed police, typically wear 'business attire' in bureaucratic and investigative functions where a uniformed presence would be either a distraction or intimidating, but a need to establish police authority still exists. "Plainclothes" officers dress in attire consistent with that worn by the general public for purposes of blending in.

In some cases, police are assigned to work "undercover", where they conceal their police identity to investigate crimes, such as organized crime or narcotics crime, that are unsolvable by other means. In some cases this type of policing shares aspects with espionage.

The relationship between detective and uniformed branches varies by country. In the United States, there is high variation within the country itself. Many US police departments require detectives to spend some time on temporary assignments in the patrol division. The argument is that rotating officers helps the detectives to better understand the uniformed officers' work, to promote cross-training in a wider variety of skills, and prevent "cliques" that can contribute to corruption or other unethical behavior. Conversely, some countries regard detective work as being an entirely separate profession, with detectives working in separate agencies and recruited without having to serve in uniform. A common compromise in English-speaking countries is that most detectives are recruited from the uniformed branch, but once qualified they tend to spend the rest of their careers in the detective branch.

Another point of variation is whether detectives have extra status. In some forces, such as the New York Police Department and Philadelphia Police Department, a regular detective holds a higher rank than a regular police officer. In others, such as Law enforcement in the United Kingdom, British police forces and Law enforcement in Canada, Canadian police forces, a regular detective has equal status with regular uniformed officers. Officers still have to take exams to move to the detective branch, but the move is regarded as being a specialization, rather than a promotion.

Volunteers and auxiliary

Police services often include part-time or volunteer officers, some of whom have other jobs outside policing. These may be paid positions or entirely volunteer. These are known by a variety of names, such as reserves, auxiliary police or special constables.

Other volunteer organizations work with the police and perform some of their duties. Groups in the U.S. including Retired and Senior Volunteer Program, Community Emergency Response Team and the Boy Scout's Law Enforcement Exploring, Police Explorers provide training, traffic and crowd control, disaster response and other policing duties. In the U.S., the Volunteers in Police Service program assists over 200,000 volunteers in almost 2,000 programs. Volunteers may also work on the support staff. Examples of these schemes are Volunteers in Police Service in the US, Po
