It's all fun and games until someone gets shot. Five people were injured by accidental gunfire at three gun shows across the U.S. on Saturday. At the Dixie and Knife gun show in Raleigh, N.C., three people were wounded when a shotgun discharged at a security checkpoint. Fifty-four-year-old Emory L. Cozee accidentally shot himself while leaving the Indy 500 Gun and Knife Show in Indianapolis, even though loaded personal weapons are not allowed at the show. Finally, a man in Ohio was wounded in the arm and leg when a gun dealer was checking out a handgun he had just bought and accidentally pulled the trigger.
