Hopefully this leads to a nationwide repeal at some point. All the shootings in Post Offices were done by USPS employees, giving us the term, “going postal”. And you want me to walk in there without the ability to defend myself??? 
These are properties that probably get the most foot traffic by citizens and it’s a massive pain in the rump if you’re someone who carries. For a while, I had to go to the PO at least once/week and dreaded it every time. As a general rule, I avoid the PO as much as possible.
