Crime Analysis
Crime analysis is a law enforcement function that involves systematic analysis for identifying and analyzing patterns and trends in crime and disorder. Information on patterns can help law enforcement agencies deploy resources in a more effective manner, and assist detectives in identifying and apprehending suspects. Crime analysis also plays a role in devising solutions to crime problems, and formulating crime prevention strategies. Quantitative social science data analysis methods are part of the crime analysis process, though qualitative methods such as examining police report narratives also play a role. Functions Crime analysis can occur at various levels, including tactical, operational, and strategic. Crime analysts study crime reports, arrests reports, and police calls for service to identify emerging patterns, series, and trends as quickly as possible. They analyze these phenomena for all relevant factors, sometimes predict or forecast future occurrences, and issue bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crime
In ordinary language, a crime is an unlawful act punishable by a State (polity), state or other authority. The term ''crime'' does not, in modern criminal law, have any simple and universally accepted definition,Farmer, Lindsay: "Crime, definitions of", in Cane and Conoghan (editors), ''The New Oxford Companion to Law'', Oxford University Press, 2008 (), p. 263Google Books). though statutory definitions have been provided for certain purposes. The most popular view is that crime is a Category of being, category created by law; in other words, something is a crime if declared as such by the relevant and applicable law. One proposed definition is that a crime or offence (or criminal offence) is an act harmful not only to some individual but also to a community, society, or the state ("a public wrong"). Such acts are forbidden and punishable by law. The notion that acts such as murder, rape, and theft are to be prohibited exists worldwide. What precisely is a criminal offence is def ...

Data Mining
Data mining is the process of extracting and finding patterns in massive data sets involving methods at the intersection of machine learning, statistics, and database systems. Data mining is an interdisciplinary subfield of computer science and statistics with an overall goal of extracting information (with intelligent methods) from a data set and transforming the information into a comprehensible structure for further use. Data mining is the analysis step of the " knowledge discovery in databases" process, or KDD. Aside from the raw analysis step, it also involves database and data management aspects, data pre-processing, model and inference considerations, interestingness metrics, complexity considerations, post-processing of discovered structures, visualization, and online updating. The term "data mining" is a misnomer because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction (''mining'') of data itself. It also is a buzzwo ...

Law Enforcement Techniques
Law is a set of rules that are created and are law enforcement, enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a Social science#Law, science and as the art of justice. State-enforced laws can be made by a legislature, resulting in statutes; by the executive through decrees and regulations; or by judges' decisions, which form precedent in common law jurisdictions. An autocrat may exercise those functions within their realm. 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 also serves as a mediator of relations between people. Legal systems vary between Jurisdiction (area), jurisdictions, with their differences analysed in comparative law. In Civil law (legal system), civil law jurisdictions, a legislature or othe ...

Forensic
Forensic science combines principles of law and science to investigate criminal activity. Through crime scene investigations and laboratory analysis, forensic scientists are able to link suspects to evidence. An example is determining the time and cause of death through autopsies. This evidence can then be used for proof towards a crime. Forensic science, often confused with criminalistics, is the application of science principles and methods to support legal decision-making in matters of criminal and civil law. During criminal investigation in particular, it is governed by the legal standards of admissible evidence and criminal procedure. It is a broad field utilizing numerous practices such as the analysis of DNA, fingerprints, bloodstain patterns, firearms, ballistics, toxicology, microscopy, and fire debris analysis. Forensic scientists collect, preserve, and analyze evidence during the course of an investigation. While some forensic scientists travel to the scene of ...

Crime Scene
A crime scene is any location that may be associated with a committed crime. Crime scenes contain physical evidence that is pertinent to a criminal investigation. This evidence is collected by crime scene investigators (CSI) and law enforcement. The location of a crime scene can be the place where the crime took place or can be any area that contains evidence from the crime itself. Scenes are not only limited to a location, but can be any person, place, or object associated with the criminal behaviours that occurred. Immediately after the discovery of a crime scene, measures must be taken to secure and protect the scene from contamination. To maintain the integrity of the scene, law enforcement must take action to block off the surrounding area as well as keep track of who comes in and goes out. By taking these precautions, officers can ensure that evidence that is collected can be used in court. Evidence that has become contaminated, tampered with, or mistreated can pollute th ...

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 - What is POP?

Community Policing
Community policing is a philosophy and organizational strategy whereby law enforcement cooperates with community groups and citizens in producing safety and security. The theory underlying community policing is that it makes citizens more likely to cooperate with police by changing public perceptions of both the intention and capacity of the police. The theory is also that it changes attitudes of police officers and increases accountability. Scholarship has raised questions about whether community policing leads to improved outcomes. History Values of community policing have been linked to Sir Robert Peel's 1829 Peelian Principles, most notably John Alderson, the former Chief Constable of Devon and Cornwall Police. Peel's ideas included that the police needed to seek the cooperation of the public and prioritize crime prevention. The term "community policing" came into use in the late 20th century, and then only as a response to a preceding philosophy of police organization. I ...

Community Oriented Policing Services
The Office of Community Oriented Policing Services (COPS Office) is a component of the United States Department of Justice. The COPS Office was established through a provision in the 1994 Violent Crime Control and Law Enforcement Act. Since 1994, the COPS Office has provided $14 billion in assistance to state and local law enforcement agencies to help hire community policing officers. The COPS Office also funds the research and development of guides, tools and training, and provides technical assistance to police departments implementing community policing Community policing is a philosophy and organizational strategy whereby law enforcement cooperates with community groups and citizens in producing safety and security.

Law Enforcement Assistance Administration
The Law Enforcement Assistance Administration (LEAA) was a U.S. federal agency within the United States Department of Justice. It administered federal funding to state and local law enforcement agencies and funded educational programs, research, state planning agencies, and local crime initiatives as part of President Lyndon B. Johnson's "war on crime" program. History The LEAA was established by the Omnibus Crime Control and Safe Streets Act of 1968 and was abolished in 1982. Its predecessor agency was the Office of Law Enforcement Assistance (1965–1968). Its successor agencies were the Office of Justice Assistance, Research, and Statistics (1982–1984) and the Office of Justice Programs. The LEAA included the National Institute of Law Enforcement and Criminal Justice, which had its functions absorbed by the National Institute of Justice on December 27, 1979, with passage of the Justice System Improvement Act of 1979. The Act, which amended the Omnibus Crime Control and Saf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Townships
A township is a form of human settlement or administrative subdivision. Its exact definition varies among countries. Although the term is occasionally associated with an urban area, this tends to be an exception to the rule. In Australia, Canada, Scotland, and parts of the United States, the term refers to settlements too small or scattered to be considered urban. Australia '' The Australian National Dictionary'' defines a township as "a site reserved for and laid out as a town; such a site at an early stage of its occupation and development; a small town". The term refers purely to the settlement; it does not refer to a unit of government. Townships are governed as part of a larger council (such as that of a shire, district or city) or authority. Canada In Canada, two kinds of township occur in common use: *In Eastern Canada, a township is one form of the subdivision of a county. In Canadian French, this is a .
