I heartily support the Right of all people to carry/keep/collect/responsibly use any type of "arms" they wish to employ. Pistol, rifle, shotgun, laser, full auto, muzzle loader, sharp edged, lead filled, crew served, multiple impact re-entry vehicle, etc... that they can afford to buy and safely use without infringing on the equal Rights of others.
I just think it's stupid to look weak and an easy mark.
Back in ‘01, January in DC, had a taxi driver named Aziz from Afghanistan.
He said I have a tank, my neighbor has rockets.
So there is peace. Heh.
