Active Self Protection

Our local post office utilizes a city-owned and city-managed parking lot that is shared with other businesses and downtown area. Since USPS does not own nor control this parking lot, does the no firearm law regarding "All real property under the charge and control of the Postal Service" not apply here?

Our business does daily drop-offs at the post office, and I want to confirm if leaving a firearm secured in the locked vehicle is allowed since this is a city-owned and operated parking lot, and not controlled by the USPS?

I would be really careful. There is a court case about post offices right now that looks promising but I personally wouldn’t want the Feds trying to make an example out of me.

Yeah, at the state level, Ohio cleared up the bit about when you're in your car, even on private (such as your employer's) property, you are on *your* property until your foot hits the floor.

But Fed level? Definitely would keep my legal eyes open.

If memory serves, BONIDY v. UNITED STATES POSTAL SERVICE
didn't go so well.

US v. Emmanuel Ayala holds some promise. Not sure if that's the one to which John refers.

THs situation you describe, where the P.O. leases a space in a commercial or public building, means the parking may be is safe for carry. You still have to del with the prohibition in the PO interior space.
But, as usual, when the entire building and gronds are P.O., the prohibiution applies to the parking lot, also. Further, since it is city owned and oeprated, you must research state and local laws on firearms in theri property.
THe recent decision was from a District Court, so has no bearing on teh rest of the country beyond that one case. We can hope it escalates to teh Circuit Court and then to the Supreme Court..

I got some clarification from a window clerk who is also a CCW permit holder. He stated that everything from the building side of the sidewalk/curb is postal property - and they have zero control or authority over the town owned/operated public parking space. I'm waiting for the postmaster to get back to confirm.
