Stacey Cornell Koon (born November 23, 1950) is an American former policeman with the Los Angeles Police Department.

[4] On March 3, 1991, in Los Angeles, a high-speed chase was initiated by California Highway Patrol officer Melanie Singer after motorist Rodney King was observed driving a 1988 white Hyundai automobile 100 miles per hour (160 km/h).

In 1993, the four policemen were tried in a federal court in Los Angeles; Koon and Powell were convicted of violating King's civil rights.

[8][9] Koon wrote a book in 1992 about the incident, entitled Presumed Guilty: The Tragedy of the Rodney King Affair in which he defended his actions and blamed the riots on the media and community leaders.

[3] In 2012, he began working as a chauffeur in Los Angeles for the limousine company Music Express where his patrons have included former U.S. vice president Al Gore and political commentator D. L. Hughley as well as other prominent Hollywood writers.

[13][14] Both Koon and fellow LAPD officer Laurence Powell have been used as symbols of racism in hip hop and related music.

[16] Koon pleaded no contest and received a sentence of three years' probation and was required to install an alcohol interlock on his vehicle.
