Watts Riots of 1965 and The Rodney King Los Angeles riots of 1992 were the result of police brutality after a suspicion of driving while intoxicated traffic stops.
Lee Minikus, a California Highway Patrol motorcycle officer, pulled over Marquette Frye, who Minikus believed was intoxicated because of his observed erratic driving. Frye failed to pass sobriety tests; including walking in a straight line and touching his nose, and was arrested soon after. Minikus refused to let Frye’s brother, Ronald, drive the car home, and radioed for it to be impounded. By the time the riot subsided, 34 people had been killed, 1,032 injured, and 3,952 arrested
