It's still what Sammitch was talking about: you can never predict what's gonna happen. I'm gonna go with the odds and trust that I won't need a gun. I don't think guns are necessary if you live in an urban area... if anything, buying one raises the possibilities that something dangerous will fall in the wrong hands. In modern life, guns are toys for grown men. That's why I have no problem with their purchase being as restricted as it possibly could be.
