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 police officers, special police officers, customs officers, state troopers, special agents, special investigators, border patrol officers, immigration officers, court bailiffs, correctional officers, detention officers, county jailers ,probation officers, parole officers, arson investigators, auxiliary officers, game wardens, sheriffs, constables, marshals, and  deputies. 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. Although typically the term "law enforcement officer" refers to those government agents with police powers, prosecutors are also law enforcement officers.
