The violence began about 9 p.m. along West Florissant Avenue, one of the city’s main streets, within two blocks of where Michael Brown, an unarmed black teenager, was fatally shot. Hundreds of police officers turned out in riot gear, shooting rubber bullets and firing canisters of tear gas in an effort to disperse protesters. Some in the crowd retrieved the smoking canisters and threw them back toward the officers.
