Police Science
Police science is the study and research which deals with police work. Studies and research in criminology, forensic science, psychiatry, psychology, jurisprudence, community policing, criminal justice, correctional administration and penology all come under this umbrella term 'police science'. It thus includes physical and social sciences. By country United Kingdom UK has developed the Police National Computer as a sophisticated intelligence tool that holds extensive data on criminals, vehicles and property, and accessible in a matter of seconds through over 30,000 terminals across the country. PITO reports that a national fingerprint and DNA database has been developed containing over 3.4 million DNA profiles providing the police with an average of 3,000 matches a month. In 2004-5 there were over 40,000 matches. The police use a wide range of technologies to curb road traffic offences like speeding and drunk driving including breathalyser devices, bus lane enforcement cameras, ...

Criminology
Criminology (from Latin , "accusation", and Ancient Greek , ''-logia'', from λόγος ''logos'' meaning: "word, reason") is the study of crime and deviant behaviour. Criminology is an interdisciplinary field in both the behavioural and social sciences, which draws primarily upon the research of sociologists, political scientists, economists, psychologists, philosophers, psychiatrists, social workers, biologists, social anthropologists, as well as scholars of law. Criminologists are the people working and researching the study of crime and society's response to crime. Some criminologists examine behavioral patterns of possible criminals. Generally, criminologists conduct research and investigations, developing theories and analyzing empirical patterns. The interests of criminologists include the study of nature of crime and criminals, origins of criminal law, etiology of crime, social reaction to crime, and the functioning of law enforcement agencies and the penal insti ...

Forensic Science
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Forensic science is a broad field that includes; DNA analysis, fingerprint analysis, blood stain pattern analysis, firearms examination and ballistics, tool mark analysis, serology, toxicology, hair and fiber analysis, entomology, questioned documents, anthropology, odontology, pathology, epidemiology, footwear and tire tread analysis, drug chemistry, paint and glass analysis, digital audio video and photo analysis. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals. Still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of mental disorders. These include various maladaptations related to mood, behaviour, cognition, and perceptions. See glossary of psychiatry. Initial psychiatric assessment of a person typically begins with a case history and mental status examination. Physical examinations and psychological tests may be conducted. On occasion, neuroimaging or other neurophysiological techniques are used. Mental disorders are often diagnosed in accordance with clinical concepts listed in diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited and used by the World Health Organization (WHO) and the widely used '' Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013 which re-organized the larger categories of various diseases and expanded upon the p ...

Psychology
Psychology is the scientific study of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the natural and social sciences. Psychologists seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Ψ (''psi''), the first letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can also be classified as behavioral or cognitive scientists. Some psyc ...

Jurisprudence
Jurisprudence, or legal theory, is the theoretical study of the propriety of law. Scholars of jurisprudence seek to explain the nature of law in its most general form and they also seek to achieve a deeper understanding of legal reasoning and analogy, legal systems, legal institutions, and the proper application of law, the economic analysis of law and the role of law in society. Modern jurisprudence began in the 18th century and it was based on the first principles of natural law, civil law, and the law of nations. General jurisprudence can be divided into categories both by the type of question scholars seek to answer and by the theories of jurisprudence, or schools of thought, regarding how those questions are best answered. Contemporary philosophy of law, which deals with general jurisprudence, addresses problems internal to law and legal systems and problems of law as a social institution that relates to the larger political and social context in which it exists.Shi ...

Community Policing
Community policing, or community-oriented policing (COP), is a strategy of policing that focuses on developing relationships with community members. It is a philosophy of full-service policing that is highly personal, where an officer patrols the same area for an extended time and develops a partnership with citizens to collaboratively identify and solve problems. The goal is for police to build relationships with the community, including through local agencies to reduce antisocial behaviour and low-level crime,Brown, L. and Wycoff, M.D., "Policing Houston: reducing fear and improving services", ''Crime and Delinquency'' (Jun. 1987): 71–89.Bobinsky, Robert, "Reflections on community-oriented policing", ''FBI Law Enforcement Bulletin'' (Mar. 1994): 15–19. but the broken windows theory proposes that this can reduce serious crimes as well. Community policing is related to problem-oriented policing and intelligence-led policing, and contrasted with reactive policing strategies ...

Criminal Justice
Criminal justice is the delivery of justice to those who have been accused of committing crimes. The criminal justice system is a series of government agencies and institutions. Goals include the Rehabilitation (penology), rehabilitation of offenders, preventing other crimes, and moral support for victims. The primary institutions of the criminal justice system are the police, Prosecutor, prosecution and Criminal defense lawyer, defense lawyers, the courts and the prisons system. Criminal justice system Definition The criminal justice system consists of three main parts: #Law enforcement agencies, usually the police #Courts and accompanying Prosecutor, prosecution and Criminal defense lawyer, defence lawyers #Agencies for detaining and supervising offenders, such as prisons and probation agencies. In the criminal justice system, these distinct agencies operate together as the principal means of maintaining the rule of law within society. Law enforcement The first contact a ...

Penology
Penology (from "penal", Latin ''poena'', "punishment" and the Greek suffix '' -logia'', "study of") is a sub-component of criminology that deals with the philosophy and practice of various societies in their attempts to repress criminal activities, and satisfy public opinion via an appropriate treatment regime for persons convicted of criminal offences. The Oxford English Dictionary defines penology as "the study of the punishment of crime and prison management," and in this sense it is equivalent with corrections. Penology is concerned with the effectiveness of those social processes devised and adopted for the prevention of crime, via the repression or inhibition of criminal intent via the fear of punishment. The study of penology therefore deals with the treatment of prisoners and the subsequent rehabilitation of convicted criminals. It also encompasses aspects of probation (rehabilitation of offenders in the community) as well as penitentiary science relating to the secure de ...

Police National Computer
The Police National Computer (PNC) is a database used by law enforcement organisations across the United Kingdom and other Non-Law Enforcement Agencies. Originally developed in the early 1970s, PNC1 went 'live' in 1974 providing UK police forces with online access to the Lost/Stolen vehicle database. The vehicle owners application quickly followed giving the police online access to the names/addresses of every vehicle owner in the UK. The Police National Computer started holding nominal information based on the computerisation of criminal records held by the Metropolitan Police and other police forces in the late 1970s. These CRO records could be accessed online in real-time by all UK police forces via the "Names" applications. The PNC now consists of several databases available 24 hours a day, giving access to information of national and local matters. As of 18 January 2021, Kit Malthouse said that there are 13 million person records, 58.5 million driver records, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Database
A DNA database or DNA databank is a database of DNA profiles which can be used in the analysis of genetic diseases, genetic fingerprinting for criminology, or genetic genealogy. DNA databases may be public or private, the largest ones being national DNA databases. DNA databases are often employed in forensic investigations. When a match is made from a national DNA database to link a crime scene to a person whose DNA profile is stored on a database, that link is often referred to as a ''cold hit''. A cold hit is of particular value in linking a specific person to a crime scene, but is of less evidential value than a DNA match made without the use of a DNA database. Research shows that DNA databases of criminal offenders reduce crime rates. Types Forensic A forensic database is a centralized DNA database for storing DNA profiles of individuals that enables searching and comparing of DNA samples collected from a crime scene against stored profiles. The most important function o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breathalyser
A breathalyzer or breathalyser (a portmanteau of ''breath'' and ''analyzer/analyser'') is a device for estimating blood alcohol content (BAC), or to detect viruses or diseases from a breath sample. The name is a genericized trademark of the Breathalyzer brand name of instruments developed by inventor Robert Frank Borkenstein in the 1950s. Origins A 1927 paper produced by Emil Bogen, who collected air in a football bladder and then tested this air for traces of alcohol, discovered that the alcohol content of 2 litres of expired air was a little greater than that of 1 cc of urine. However, research into the possibilities of using breath to test for alcohol in a person's body dates as far back as 1874, when Francis E. Anstie made the observation that small amounts of alcohol were excreted in breath. Also, in 1927 a Chicago chemist, William Duncan McNally, invented a breathalyzer in which the breath moving through chemicals in water would change color. One use for his ...
