A law enforcement officer (LEO), or peace officer in North American English, is a public-sector employee whose duties primarily involve the enforcement of laws. The phrase can include campaign disclosure specialists, police officers, prosecutors (who are law enforcement officers but not peace officers), municipal law enforcement officers, health inspectors, special police officers, customs officers, lawyers, state troopers, federal agents, secret agents, special investigators, coast guards, border patrol officers, judges, district attorney, bounty hunters, gendarmerie officers, immigration officers, private investigators, court officers, probation officers, parole officers, arson investigators, auxiliary officers, animal control officers, game wardens, park rangers, county sheriffs, constables, marshals, deputies, detention officers, correction officers, sworn campus police officers and public safety officers (at public and private institutions). Security guards are civilians and therefore not law enforcement officers, unless they have been granted powers to enforce particular laws, such as those accredited under a community safety accreditation scheme such as a security police officer.
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—traditionally, anyone "sworn, badged, and armable" who can arrest, or refer such arrest for a criminal prosecution. Hence, city police officers, county sheriffs' deputies, state troopers and in some states corrections officers are usually vested with the same authority within a given jurisdiction. Contract security officers may enforce certain laws and administrative regulations, which may include detainment or apprehension authority, including arresting. Peace officers may also be able to perform all duties that a law enforcement officer is tasked with, but may or may not be armed with a weapon.
In Canada, the Criminal Code (R.S., c. C-34, s. 2.) defines a peace officer as:
Peace officer includes
- (a) a mayor, warden, reeve, sheriff, deputy sheriff, sheriff's officer, and justice of the peace,
- (b) a member of the Correctional Service of Canada who is designated as a peace officer pursuant to Part I of the Corrections and Conditional Release Act, and a warden, deputy warden, instructor, keeper, jailer, guard and any other officer or permanent employee of a prison other than a penitentiary as defined in Part I of the Corrections and Conditional Release Act,
- (c) a police officer, police constable, bailiff, constable, or other person employed for the preservation and maintenance of the public peace or the service or execution of civil process,
- (d) an officer within the meaning of the Customs Act, the Excise Act or the Excise Act, 2001, or a person having the powers of such an officer, when performing any duty in the administration of any of those Acts,
- (d.1) an officer authorized under subsection 138(1) of the Immigration and Refugee Protection Act,
- (e) a person designated as a fishery guardian under the Fisheries Act when performing any duties or functions under that Act and a person designated as a fishery officer under the Fisheries Act when performing any duties or functions under that Act or the Coastal Fisheries Protection Act,
- (f) the pilot in command of an aircraft
- (i) registered in Canada under regulations made under the Aeronautics Act, or
- (ii) leased without crew and operated by a person who is qualified under regulations made under the Aeronautics Act to be registered as the owner of an aircraft registered in Canada under those regulations, while the aircraft is in flight, and
- (g) officers and non-commissioned members of the Canadian Forces who are
- (i) appointed for the purposes of section 156 of the National Defence Act, (Military Police) or
- (ii) employed on duties that the Governor in Council, in regulations made under the National Defence Act for this paragraph, has prescribed to be of such a kind as to necessitate that the officers and non-commissioned members performing them have the powers of peace officers;
*10. The Commissioner may in writing designate any staff member, either by name or by class, to be a peace officer, and a staff member so designated has all the powers, authority, protection and privileges that a peace officer has by law in respect of
- (a) an offender subject to a warrant or an order for long-term supervision; and
- (b) any person, while the person is in a penitentiary.
Also, provincial legislatures can designate a class of officers (i.e. Conservation Officers, Park Rangers and Commercial Vehicle Safety and Enforcement) to be peace officers.
Under the Code Of Criminal Procedure a peace officer includes all police officers, a Divisional Assistant Government Agent and a Grama Niladharis appointed by a Government Agent (GA) in writing to perform police duties or keep the peace. A peace officer has the power to arrest a person without a warrant or an order from a magistrate under certain circumstances such as;
- who in his presence commits any breach of the peace,
- who has been concerned in any cognizable offense or against whom a reasonable complaint has been made or credible information has been received or a reasonable suspicion exists of his having been so concerned,
- having in his possession without lawful excuse any implement of house-breaking,
- who has been proclaimed as an offender,
- in whose possession anything is found which may reasonably be suspected to be property stolen or fraudulently obtained and who may reasonably be suspected of having committed an offense concerning such thing
- who obstructs a peace officer while in the execution of his duty or who has escaped or attempts to escape from lawful custody,
- suspected of being a military deserter,
- suspected of concealing his presence under circumstances which afford reason to believe that he is taking such precautions intending to commit a cognizable offense,
- who has been concerned in or against whom a reasonable complaint has been made or credible information has been received or a reasonable suspicion exists of his having been concerned in any act committed at any place out of Sri Lanka
During the British colonial administration of Ceylon, when uniformed policing by the Ceylon Police Force in rural areas of the island was limited, the local government agent would appoint individuals from wealthy influential families deemed loyal to the crown as a Peace Officers with police powers to keep the peace. This was an influential post, the holder had much control over the people of the area. Commonly a Native Headman (Ralahami) was appointed as the Peace Officer to maintain law and order in rural villages.
Following the formation of the State Council of Ceylon in 1931, one of its members, H. W. Amarasuriya, called for an inquiry into the headman system. A commission was formed made up of retired civil servants and lawyers headed by H.M. Wedderburn. The commission reported on reforming the headman system or replacing it with transferable District Revenue Officers. The headman system was abolished as an administrative system, with the titles of Mudaliyar (Mudali - මුදලි) and Muhandiram retained by the government to be awarded as honors. This practice remained until the suspension of Ceylonese honors in 1956 by S. W. R. D. Bandaranaike. The minor headman positions were retained, surviving well into the 1970s when the post of Vidane was replaced with the transferable post of Grama Niladhari (Village Officer).

Most peace officers have jurisdiction throughout the state, but many have limited powers outside their political subdivisions. Some peace officers require special permission to carry firearms. Powers are often limited to the performance of peace officers' primary duties (usually, enforcement of specific laws within their political subdivision); however, most have power of arrest anywhere in the state for any public offense that poses an immediate danger to a person or property.
A private person (i.e., ordinary citizen) may arrest another person for an offense committed in the arresting person's presence, or if the other person has committed a felony whether or not in the arresting person's presence (Penal Code § 837), though such an arrest when an offense has not occurred leaves a private person open to criminal prosecution and civil liability for false arrest. A peace officer may:
- without an arrest warrant, arrest a person on probable cause that the person has committed an offense in the officer's presence, or if there is probable cause that a felony has been committed and the officer has probable cause to believe the person to be arrested committed the felony. (Penal Code § 836).
- Is immune from civil liability for false arrest if, at the time of arrest, the officer had probable cause to believe the arrest was lawful.
Persons are required to comply with certain instructions given by a peace officer, and certain acts (e.g., battery) committed against a peace officer carry more severe penalties than the same acts against a private person. It is unlawful to resist, delay, or obstruct a peace officer in the course of the officer's duties (Penal Code § 148[a]).
New York StateEdit
New York State grants peace officers very specific powers under NYS Criminal Procedure Law, that they may make warrantless arrests, use physical and deadly force, and issue summonses under section 2.20 of that law.
There is a full list of peace officers under Section 2.10 of that law. Below are some examples.
- That state has law enforcement agencies contained within existing executive branch departments that employ sworn peace officers to investigate and enforce laws specifically related to the department. Most often, these departments employ sworn Investigators (separate from the New York State Police) that have statewide investigative authority under the department's mission.
- The New York State Bureau of Narcotic Enforcement (BNE) is a state investigative agency housed under the State Department of Health. Narcotic Investigators with the Bureau of Narcotic Enforcement are sworn peace officers who carry firearms, make arrests, and enforce the New York State Controlled Substances Act, New York State Penal Law, and New York State Public Health Law.
- The New York State Department of Taxation and Finance employs sworn peace officers as Excise Tax Investigators and Revenue Crimes Investigators. These State Investigators carry firearms, make arrests, and enforce New York State Penal Law related to tax evasion and other crimes. Excise Tax Investigators may execute Search Warrants.
- The New York State Department of Motor Vehicles (DMV) Division of Field Investigation also employ sworn peace officers as State Investigators. All DMV Investigators carry Glock 23 firearms and enforce New York State Penal Law and New York Vehicle and Traffic Law. The DMV Division of Field Investigation investigates auto theft, odometer tampering, fraudulent documents, and identity theft crimes.
