That said, I'm sure we all wish the Sandy Hook principal had been able to rush the mad gunner with a loaded Colt's Baby Dragoon instead of just her bare hands. She'd be alive today, and that SOB would still be dead, but without taking all those little kids and teachers with him, the sorry b@stard.
That would certainly have canceled his check ... my point is legal, not mechanical or tactical. Folks are sometimes surprised to see muzzleloaders sold by internet, or over the counter with no forms, no NICS, etc.
