Sorry, couldn't resist. We used to use that line back in the day! The only reason the AP and other commie rags are running these stories and the reason Holder is bitching about them is to try to fool the American public, the non gun owning part of the American public, into accepting strict gun laws that take away ALL of our firearms. It is already illegal to won full auto weapons without a special permit, and most people aren't going to try and get one, and full autos are not available in most gun stores. Why would they carry something there is not much of a market for?
All lies with one aim, to disarm us folks, so bambi and the boys can do what they want with impunity.
If someone, including, and probably especially, the government, wants to disarm you they do NOT have your welfare in mind.
