Really? They disprove it how? You obviously have never been in the military or else you wouldn't be stupid enough to believe that the soldiers on Ft. Hood had access to firearms and ammo. They don't. It's one of the cruel ironies of military life. You almost never see ammunition unless you are being sent into combat or you're on the qualification range. The guns are kept in armored vaults.

The people murdered at Ft. Hood were unarmed and helpless. The people they relied upon to stop the killing were actually civilian police.
