"The need to restrain our own government."

it doesn't work. Your government spies on your every move and allows corporations to do the same. It gathers data on where you are, allows business to construct profiles of you to target advertising and who knows what else. Your phone allows them to track your physical movements. They're fucking you (and everyone else) over and all your guns can't do a thing about it. Heck, most people don't even know it's happening.

Your gun might allow you to take a pot-shot at a soldier or copper, but it's useless in the face of threats to your freedom other than violence, and even then if it's between you and a marine I know who'd I be betting on.
