"I think the gangbangers would have them if they could get them. And I'd rather they didn't".
Just like the laws against crack, heroin, and cocaine have kept the gangbangers from getting them.
When is the last time you heard a gangbanger ripping off a magazine with a fully automatic weapon? When is the last time you heard of a gangbanger firing a pistol? The sad fact is that because pistols are easy to get, they are the weapon of choice. I think we would both agree that the gangbanging punks would absolutely LOVE to get their incompetent paws on a fully automatic weapon; then they would have to use it in order to impress the "bros".
