On this date in 1965, a minor scuffle following a traffic stop in Los Angeles would escalate into what would become known as the Watts riots. The unrest would continue until August 17th. When it was all over, 34 people were killed, over 1000 injured, and 3400 arrested. Almost a thousand buildings, mostly businesses, were damaged or destroyed. Damage was estimated to be about $40 million.
