Bases are pretty anal about weapons. The local base store sells weapons but they have signs up that you have to register them if you live on base within days or leave immediately if you don’t. I’m guessing that right after you buy one you can’t do any more shopping or stay on base.
They have signs up at the gates about no concealed weapons. Does that mean that they have to be in the open then?
Only SFS folks and LEOs can carry on bases. They don't want anyone else in the mix if anything goes down - Security folks will follow war-time conventions in taking out anyone who isn't them, that shows a weapon.
Active Shooter instructions are a hoot - try to hide (but you aren't allowed to move out of your building because they call for a complete lockdown. If the shooter finds you, they tell you to throw things at him. I guess they feel that giving you a stapler against a shooter is a fair trade for insuring that only they and the bad guys have weapons.
