They'd also say that anyone who uses such weaponry for criminal purposes be shown a hangnoose. Owning a firearm is a Right; no question there. Owning a firearm is also a responsibility. Seems 21st Century America has forgotten about that part of being a nation of Free men.... . . the right to a free state and the right for us to overthrow a tyrannical government.
