Stephen Paddock was probably just acting in self-defense, I bet. Yeah ... him and that kid in Florida. Just defending themselves.
No dumbass, that was murder. Illegal regardless of how its carried out.
Do you really believe people equate mass murder with self defense? If so, forget the library. Seek professional help.
I'm saying that I think it would be excellent and humorous if some of that self-defense made its way into an NRA convention. Then you guys would get to test the theory that all you need to stop a bad guy with a gun is a good guy with a gun.
