A city of Milwaukee employee cleans up a gutted Jet Beauty Supply, which was destroyed by fire and looting, in Milwaukee on Sunday, Aug. 14, 2016. The black man whose killing by police touched off rioting in Milwaukee was shot by a black officer after turning toward him with a gun in his hand, the police chief said Sunday, as Wisconsin's governor put the National Guard on standby against any further violence on the city's mostly black north side.
