The Algiers Motel incident occurred in Detroit, Michigan, United States, throughout the night of July 25–26, 1967, during the racially charged 12th Street Riot. At the Algiers Motel, approximately one mile east of where the riot began, three civilians were killed and nine others abused by a riot task force composed of the Detroit Police Department, the Michigan State Police, and the Michigan Army National Guard. Among the casualties were three black teenage boys killed, and two white women and seven black men wounded as a result. The task force was searching the area after reports were received that a gunman or group of gunmen, possibly snipers, had been seen at or near the motel.

A starting pistol or starter pistol is a blank handgun or, more recently, an electronic toy gun or device with a button connected to a sound system that is fired to start track and field races as well as some competitive swimming races. Traditional starter guns cannot fire real ammunition without first being extensively modified: Blank shells or caps are used to prevent expelling projectiles, and only a small amount of smoke can be seen when shot. In most places, trying to modify the replica is illegal.
