Several hurt at gun shows on Saturday. At a gun show in Raleigh, N.C. a 12 gauge shotgun discharged as the owner unzipped the case to let security check it at the entrance. Three were hit and injured. At a gun show in Indianapolis, IN a man accidentally shot himself as he was leaving the show. He was loading his .45 caliber semi-automatic pistol when he shot himself in the hand. And in Medina, OH a gun dealer was checking out a semi-automatic handgun that he had bought at the gun show when he accidentally pulled the trigger. The magazine had been removed from gun but there was one round left in chamber. The bullet ricocheted off floor and hit the owners friend in the leg and arm.
