Let me make a comparison just so you can decide the rationality of your statement. If this is the case then you should ban all alcohol(guns) sales. Lots of innocent people(Joe getting his pizza) die everyday from drunk drivers(nutters/criminals with guns). But you don't ban all alcohol sales, because as we know from experience that leads to gangs taking over and creating more death than the product itself. This next part is streching, but. Think about it that innocent person(joe getting his pizza) had been drunk(had a gun) too. He wouldn't have tensed up and might have walked away like most drunk drivers(nutter/criminal with a gun). If you don't want to drink you don't have to but you are accepting that you have no defence.
