Problem-oriented Policing
Problem-oriented policing (POP), coined by University of Wisconsin–Madison professor Herman Goldstein, is a policing strategy that involves the identification and analysis of specific crime and disorder problems, in order to develop effective response strategies. POP requires police to identify and target underlying problems that can lead to crime. Goldstein suggested it as an improvement on the reactive, incident-driven “standard model of policing”. Goldstein's 1979 model was expanded in 1987 by John E. Eck and William Spelman into the Scanning, Analysis, Response, and Assessment (SARA) model for problem solving.Center for Problem Oriented Policing

University Of Wisconsin–Madison
A university () is an educational institution, institution of higher education, higher (or Tertiary education, tertiary) education and research which awards academic degrees in several Discipline (academia), academic disciplines. Universities typically offer both undergraduate education, undergraduate and postgraduate education, postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation ...

Law Enforcement Techniques
Law is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior,Robertson, ''Crimes against humanity'', 90. with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions. Private individuals may create legally binding contracts, including arbitration agreements that adopt alternative ways of resolving disputes to standard court litigation. The creation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people. Legal systems vary between jurisdictions, ...

Neighbourhood Policing Team
A neighbourhood policing team (NPT), also sometimes known as safer neighbourhood team (SNT), is a small team of police officers and police community support officers (usually 3-10 strong) who are dedicated to policing a certain community or area. It is a concept developed by the police of the United Kingdom. , there are 3,600 NPTs throughout the United Kingdom. This type of policing is designed to make the police more visible, reduce fear and aid interaction between the public and the police, and it aids in local knowledge, gaining intelligence and tip-offs from the public. NPTs are led by a police officer, usually of sergeant or inspector rank, and may include police community support officers, special constables, local council staff and members of voluntary organisations, such as a neighbourhood watch. Usually NPTs are responsible for patrolling an area of around of urban area or around of rural area. See also *Community policing * Community Beat Manager *Police pat ...

Peelian Principles
The Peelian principles summarise the ideas that Sir Robert Peel developed to define an ethical police force. The approach expressed in these principles is commonly known as policing by consent in the United Kingdom and other countries such as Ireland, Canada, Australia, and New Zealand. In this model of policing, police officers are regarded as citizens in uniform. They exercise their powers to police their fellow citizens with the implicit consent of those fellow citizens. "Policing by consent" indicates that the legitimacy of policing in the eyes of the public is based upon a general consensus of support that follows from transparency about their powers, their integrity in exercising those powers and their accountability for doing so. Historical background In early 19th-century Britain, attempts by the government to set up a police force for London were met with opposition. People were suspicious of the idea of a large and possibly armed police force, and feared that it cou ...

Evidence-based Policing
Evidence-based policing (EBP) is an approach to policy making and tactical decision-making for police departments. It has its roots in the larger movement towards evidence-based practices. Advocates of evidence-based policing emphasize the value of statistical analysis, empirical research and ideally randomized controlled trials. EBP does not dismiss more traditional drivers of police decision-making, but seeks to raise awareness and increase the application of scientific testing, targeting and tracking of police resources, especially during times of budget cuts and greater public scrutiny. Origins Experiments had been used in earlier decades to find better policing methods, before Lawrence Sherman first outlined a definition of "evidence-based policing" in 1998. The Police Foundation was founded in 1970. In 1971-72 the Police Foundation worked with the Kansas City Police Department to carry out a landmark study on patrol cars in what is known as the Kansas City preventive pa ...

Intelligence-led Policing
Intelligence-led policing (ILP) is a policing model built around the assessment and management of risk.Willem de Lint, “Intelligence in Policing and Security: Reflections on Scholarship,” Policing & Society, Vol. 16, no. 1 (March 2006): 1-6. Intelligence officers serve as guides to operations, rather than operations guiding intelligence.Royal Canadian Mounted Police“Intelligence-led policing: A Definition,” RCMP Criminal Intelligence Program. Retrieved 13 June 2007. Calls for intelligence-led policing originated in the 1990s, both in Britain and in the United States. In the U.S., Mark Riebling's 1994 book Wedge - The Secret War between the FBI and CIA spotlighted the conflict between law enforcement and intelligence, and urged cops to become "more like spies." Intelligence-led policing gained considerable momentum globally following the September 11 terrorist attacks on the United States. It is now advocated by the leading police associations in North America and the UK ...

Broken Windows Theory
In criminology, the broken windows theory states that visible signs of crime, anti-social behavior and civil disorder create an urban environment that encourages further crime and disorder, including serious crimes. The theory suggests that policing methods that target minor crimes such as vandalism, loitering, public drinking, jaywalking, and fare evasion help to create an atmosphere of order and lawfulness. The theory was introduced in a 1982 article by social scientists James Q. Wilson and George L. Kelling. It was popularized in the 1990s by New York City police commissioner William Bratton and mayor Rudy Giuliani, whose policing policies were influenced by the theory. The theory became subject to debate both within the social sciences and the public sphere. Broken windows policing has been enforced with controversial police practices, such as the high use of stop-and-frisk in New York City in the decade up to 2013. In response, Bratton and Kelling have written that broken ...

Crime Displacement
Crime displacement is the relocation of crime (or criminals) as a result of police crime-prevention efforts. Crime displacement has been linked to problem-oriented policing, but it may occur at other levels and for other reasons. Community-development efforts may be a reason why criminals move to other areas for their criminal activity. The idea behind displacement is that when motivated criminal offenders are deterred, they will commit crimes elsewhere. Geographic police initiatives include assigning police officers to specific districts so they become familiar with residents and their problems, creating a bond between law-enforcement agencies and the community. These initiatives complement crime displacement, and are a form of crime prevention. Experts in the area of crime displacement include Kate Bowers, Rob T. Guerette, and John E. Eck. Key concepts Six types of crime displacement have been identified and defined. The first is ''temporal displacement'', which involves crim ...

Community Oriented 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 ...

Randomized Controlled Trial
A randomized controlled trial (or randomized control trial; RCT) is a form of scientific experiment used to control factors not under direct experimental control. Examples of RCTs are clinical trials that compare the effects of drugs, surgical techniques, medical devices, diagnostic procedures or other medical treatments. Participants who enroll in RCTs differ from one another in known and unknown ways that can influence study outcomes, and yet cannot be directly controlled. By Random assignment, randomly allocating participants among compared treatments, an RCT enables ''statistical control'' over these influences. Provided it is designed well, conducted properly, and enrolls enough participants, an RCT may achieve sufficient control over these confounding factors to deliver a useful comparison of the treatments studied. Definition and examples An RCT in clinical research typically compares a proposed new treatment against an existing Standard of care#Medical standard of care, ...
