Maybe Piers thinks it's a AR-15 shotgun. Personally I think VP Biden is to blame for this. He's the one that told people to go get a shotgun. Well...
Just as I've posted here before. Give me a weapon, any weapon, in a confined space, and I'll kill a bunch of people before they get me, especially if I don't give a shit whether I live or die. It ain't the weapon, it's the person using it. We have yet another example of how political correctness was the fuel that allowed this to happen. That, and government bureaucracy.
