The ban was instituted in 1972. There was no ban before that.
what about face masks?
“Rights” are worthless if the government can limit them.
The PO ban is a lot of trouble for a lot of Americans who not only visit a PO on occasion but who have to get all of their mail there, as much of a problem it is if you are in a car, it keeps you defenseless if you like to pickup your mail during a walk or while bicycling.
I do not recommend anyone taking a weapon into any place where a gun is banned, in particular a court house or cop shop.
But other places such as the Post Office it could be easily done simply by having the weapon well concealed. There is just no way a gun could be detected in most places.
I personally do not take a gun into a PO, but private commercial businesses that have a No Weapons sign on there doors I say to hell with it. I will take a concealed weapon into those places. It’s well concealed and no one will ever know I have one unless I pull it out and brandish it, and I’m not that stupid. If a criminal starts gun play in such a store I will retreat and get the hell out. The gun will come out only if I am directly threatened.
When I worked at the post office I remember one of the supervisors flashing a gun at me because I refused to do over time.
Postal carriers do not need your help shooting their stupidvisor😄😃😁!
