Wikipedia: The Watts riots, sometimes referred to as the Watts Rebellion, took place in the Watts neighborhood of Los Angeles from August 11 to 16, 1965. On August 11, 1965, an African-American motorist was arrested for drunk driving. A minor roadside argument broke out, and then escalated into a fight. The community reacted in outrage to allegations of police brutality that soon spread, and six days of looting and arson followed. Los Angeles police needed the support of nearly 4,000 members of the California Army National Guard to quell the riots, which resulted in 34 deaths and over $40 million in property damage. The riots were blamed principally on police racism. It was the city’s worst unrest until the Rodney King riots of 1992.
