When i lived in Corpus Christi some anti gun clown went through the show putting ammo into guns and one got touched off.
At a gun show in Houston some idiot bought a .380, loaded it and fired it into a table just to see if it worked.
At a gun show in Spring, TX one of the dealers wanted to test a gun to see if it worked so he and the seller went to the back room, loaded the gun and fired it into a trash can.
So yes Virginia, there really are idiots at gun shows.
Even so, the numbers of DEATHS is so low as to be almost ZERO.
