Same ole story, different day...
Somebody just stirred the pot...
And the soup still ain't done!
I have a friend who is a "postal inspector" he is a federal officer and is one of the best in this field in our area...
I asked him this question about conducting lawful business in a post office while armed in accordance to state law...
He took in all of the factors in this issue, and is extremely empathetic to "our" concern over this issue...He would truely struggle with this if it ever crossed his path...
Yet he is still charged with upholding the Federal side of this, and that no carry on or about post office property (including the "public" parking area) is illegal...
"I'd hate to have to arrest and charge you, Steve"
I've not had to broach the subject with him again, ever...
