"Firearms stand next in importance to the Constitution itself. They are the people's liberty teeth keystone... the rifle and the pistol are equally indispensable... more than 99% of them by their silence indicate that they are in safe and sane hands. The very atmosphere of firearms everywhere restrains evil interference. When firearms go, all goes, we need them every hour." -George Washington, 1789
