A couple of dudes in some airplanes handily outwitted every known security device in the US arsenal and killed thousands of people. One guy with an AR-15 might not make much difference, but 50 million certainly would. Not like you have to be in combat to win a war.That;s it my man. These sorry paranoid gun religion nut jobs think their measly ar 15 and such will do anything against predator drones, tanks, well trained soldiers with infared, e.m.p.s, airstrikes and such is a funny thing.
