LOS ANGELES (AP) — Twenty years ago Sunday, thousands of people poured into the streets of South Los Angeles, furious with a jury's verdict acquitting four police officers of the videotaped beating of black motorist Rodney King.What followed was one of the nation's worst race riots, with 55 people killed and more than 2,300 injured.As a horrified nation watched on TV, white trucker Reginald Denny was beaten nearly to death.Twenty years later, much has changed in the heavily black and Hispanic section of the city where the riot began.One of Denny's attackers, Henry Keith Watson, who later apologized, is now a successful businessman. Some burned buildings have been replaced, and people say relations with police are better.But Watson and others note poverty and joblessness still remain in large measure.
