The 1991 videotaped beating of Rodney King by L.A.P.D. officers, and subsequent riots triggered by the acquittal of the officers involved, rocked L.A. and the nation. The events brought to the forefront concerns about racism and police brutality within the L.A.P.D.
The unrest began in South Central Los Angeles on April 29 after a trial jury acquitted four officers of the Los Angeles Police Department of the use of excessive force in the videotaped arrest and beating of Rodney King.
