Organisme chargé de l'application de la loiA law enforcement agency (LEA) is any government agency responsible for the enforcement of the law. LEAs which have their ability to apply their powers restricted in some way are said to operate within a jurisdiction. LEAs will have some form of geographic restriction on their ability to apply their powers. The LEA might be able to apply its powers within a country, for example the United States' Bureau of Alcohol, Tobacco, Firearms and Explosives or its Drug Enforcement Administration; within a division of a country, for example the Australian state Queensland Police; or across a collection of countries, for example international organizations such as Interpol, or the European Union's Europol.
PolicierUn policier ou agent de police est un membre de la police, qu'il porte ou non l'uniforme et dont la fonction est de faire respecter la loi, de maintenir l'ordre et d'assurer la sécurité publique. Dans la plupart des États, les policiers peuvent porter une arme pendant leur service. Ils sont représentants de l'autorité publique ; à ce titre, la loi peut alourdir les peines de certains délits tel l'outrage à agent lorsqu'il visent un policier.
Criminal justiceCriminal 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 of offenders, preventing other crimes, and moral support for victims. The primary institutions of the criminal justice system are the police, prosecution and defense lawyers, the courts and the prisons system.
Use of forceThe use of force, in the context of law enforcement, may be defined as the "amount of effort required by police to compel compliance by an unwilling subject". Use of force doctrines can be employed by law enforcement officers and military personnel on guard duty. The aim of such doctrines is to balance the needs of security with ethical concerns for the rights and well-being of intruders or suspects. Injuries to civilians tend to focus attention on self-defense as a justification and, in the event of death, the notion of justifiable homicide.
Law enforcement officerA law enforcement officer (LEO), or peace officer in North American English, is a public-sector or private-sector employee whose duties primarily involve the enforcement of laws, protecting life & property, keeping the peace, and other public safety related duties.

Modern legal codes use the term peace officer (or in some jurisdictions, law enforcement officer) to include every person vested by the legislating state with law enforcement authority.
Search and seizureSearch and seizure is a procedure used in many civil law and common law legal systems by which police or other authorities and their agents, who, suspecting that a crime has been committed, commence a search of a person's property and confiscate any relevant evidence found in connection to the crime. Some countries have certain provisions in their constitutions that provide the public with the right to be free from "unreasonable searches and seizures". This right is generally based on the premise that everyone is entitled to a reasonable right to privacy.
