By your simpleton logic then everyone in Texas should be dead and the streets should be running red with blood.
But they aren't.
A gun is a weapon. When someone looses their mind and kills people its not a big surprise. Guess what. They can also make bombs at home from stuff from the hardware store. Or better yet get in your car and drive through a crowd!
Truth is most gun deaths in America are suicides and criminals in inner cities where gun laws are most restrictive.
