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.
In 1973, the King helped steer the country out of violent clashes between student demonstrators and military rulers. His most noteworthy appearance on the political stage came in May 1992, amid violence between pro-democracy campaigners and the army.
