In my town, every now and then there's a reported robbery usually ranging from petty theft to grand theft up to about 5000 USD. Most of the time what happens is that someone breaks into a home by throwing a brick through a window and escaping out with laptops, phones, TVs, etc... Now, it's a small town and we usually get about 10 or so reported crimes a year. But does this mean we should ban bricks? Of course not because there are many uses for bricks that are non-malicious. You can use them as building materials, weights, making right angles and so on. If we were to eliminate bricks, we would be getting rid of a perfectly good material for building houses with, however, what stops people from still using bricks? The same thing can be applied to firearms. Many people own them for self-defense, hunting, or for entertainment. There are firearms related crimes, but if we were to ban firearms, it doesn't do anything to stop people from obtaining them illegally. All it really does is stop legitimate users from having them.
