I was in LA at the time of the King riots. The criminals were not all black. There were mexicans and some white people too. The police ran like chickens with their heads cut off when it started and choas followed. If the police had done their job there would have been no riots.
Before the riots the police department was being investigated for their treatment of King so they were afraid to use force to stop the riots. 50 people died. The police should have crushed the start of the riot with whatever force was needed. It was a very frightening time.
