REFILE – QUALITY REPEAT A policeman rubs his eyes after police attempted to disperse a crowd using what appeared to be teargas after a shooting incident in St. Louis, Missouri August 19, 2015. Police fatally shot a black man they say pointed a gun at them, drawing angry crowds and recalling the racial tensions sparked by the killing of an unarmed African-American teen in nearby Ferguson, Missouri, just over a year ago.
