There is always a risk of traitors like Hasan. All the more reason to allow service personnel to conceal carry while on base.
I know what you mean. The most dangerous thing for me is getting to the base. Since, I can’t even stow my weapon in my trunk, I usually just shop off-base instead. Potential Jihadi terrorists or your every-day generic gang members aside, I would prefer not to be disarmed by stupid base policies.
