What is the concern that the government knows who has guns? I've never understood why that was a concern. The government generally knows where you live, if you have a car, job, etc.......what is the concern that the gov't knows you have a gun?
Right....but how do you control the person without infringing on their civil liberties? It's a very serious thing to try and legally say that this person isn't mentally capable of doing something....and just because you're weird and antisocial doesn't mean you're not allowed to purchase a gun (or go through the loopholes).
If I'm present where you plan on mass murdering, I'm certainly going to like my chances against you with a 2x4 or rusty nail (is this a subtle Joy Ride movie reference
). I'm quick, used to be really quick, but not quicker than you with a gun after me. So for me, the difference that it makes is amount of damage in such a short amount of time.
