FERGUSON, Mo. (AP) -- A year ago, Ferguson, Missouri, was a mostly quiet working-class suburban town. The uneasy relationship between its growing black population and its mostly white police force barely registered in local headlines. Everything changed on Aug. 9, 2014, when a white police officer named Darren Wilson shot and killed Michael Brown, an unarmed black 18-year-old. The street confrontation on that sultry day launched the "Black Lives Matter" movement.
