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.
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.

Sécurité publiqueSécurité publique désigne généralement les différents aspects d'ordre public et de sécurité visant à protéger la population d'un Etat contre les menaces internes, par opposition à la sécurité extérieure qui vise la défense d'un territoire contre des menaces étrangères. Généralement, les polices nationale, municipale, la gendarmerie nationale et la douane sont chargés de veiller à la sécurité publique. En France, la direction centrale de la Sécurité publique (DCSP) est l'une des directions actives de la direction générale de la Police nationale du ministère de l'Intérieur français.
Law enforcementLaw enforcement is the activity of some members of government who act in an organized manner to enforce the law by discovering, deterring, rehabilitating, or punishing people who violate the rules and norms governing that society. The term encompasses police, courts, and corrections. These three components may operate independently of each other or collectively, through the use of record sharing and mutual cooperation. Throughout the world, law enforcement are also associated with protecting the public, life, property, and keeping the peace in society.
