So here's the deal: I have an idea for a photo involving patterns of PO boxes. I would need to purchase a PO box, take a series of photos of the single box, a wide shot of a row of them, and then merge the exposures with some fancy photoshop work.
The question is what the legality of all of this is. The post office has 24/7 video camera security (of every angle, of course). And by having an open PO box you can see into the "behind the counter" part of the the post officer, which is really just a blank white wall (but you can see it all the same).
As far as I understand the legalities of shooting on private property (and someone please correct me if I'm wrong), I would generally be allowed to shoot until they kick me out, but they wouldn't be able to get rid of any of my photos. But because the USPS is a federally mandated private enterprise with some very strict first amendment protections, I thought that the rules might be different. In addition, would being kicked out for taking photos give them permission to revoke the PO box account?
Anyone have any insights? I really want to try out this photo concept but I'm reluctant if it will get me into a legal entanglement.

Be that as it may, you still probably want to give them the benefit of a heads up.
