You just can't make people understand that as long as there is a government (ie - military) market for firearms, there will ALWAYS be guns in circulation. And as long as guns exist, you need them in the hands of the good guys to level the playing field with the bad guys that are going to have them. When it comes to acquiring illegal items, they seem to have a knack for that sort of thing.
What I find funny as that they banned guns in hopes of stopping crime. People that obviously had no problems committing crime in the first place, you assume they're going to follow another less serious law? That's like the same concept as the banks overdraft fees...you're charging us money because WE DON'T HAVE ANY MONEY? It's just blatantly backward logic!
