 Some witnesses have said they spotted a man climbing to the roof and warned local police shortly before the shooting. Sources tell the Associated Press one local officer climbed to the roof and encountered crooks who pointed his rifle at the officer. There are conflicting reports about whether the officer then retreated down the ladder or fell. The shooting killed one man in the crowd, critically injuring two others, now in stable condition. There's no place in America for this kind of violence or any violence for that matter.
