A Florida man accidentally shot himself and a co-worker while teaching the other man how to shoot a gun. The man acting as instructor shot himself in the finger Sunday afternoon while trying to unjam a 9-mm semi-automatic handgun, police said. The bullet then wounded the other man in the thigh before embedding itself in a wall, reported the Orlando Sentinel. “One of them, I guess, thought he could teach the other he could shoot,” said Sgt.
