I will relate my adventure under the waning FBHO administration. I went to mail a hand gun like I'd done dozens of times before. In my small town, the USPS people don't turn over much, so I recognized the clerks and they recognize me. So, I hand them my box and my 1508 and assume all is well. "Now, you have to give us a copy of your FFL to file when you mail these." Shocked, I whipped out my I-phone and googled up the regs and showed them that nowhere does it say that. So, i ask to talk to the local postmaster/supervisor, was promised a call back and left, went home and got a copy of my FFL, left it with them with only the first 3/last 5 showing and as much info as i thought i could get away with blacked out. I know it was surrender to stupidity, but I'd cashed the buyer's check and owed him a gun. So, a few days later I got a call; not from the postmaster, but from agent Larry from the Department of Homeland Security. Sensing this was about to go "over the cliff crazy" I decided to let him do the talking. He started talking about how they'd come to do a routine audit on the local PO and found all the 1508s they had retained. In my town of 10,000 we seem to have a lot of home based FFLs that stay busy. Sensing they were seeing a lapse in national security, they "told" the post office people that they needed to start getting a copy of the sender's FFL and the recipient's FFL if they could. This, they were certain, would stop another 9/11. So, hearing that, realizing i was not about to go to the federal pen for some unknown violation of the Patriot Act, I started laying out a scenario for agent Larry. "how about if I leave my FFL with the post office and an unscrupulous PO employee gets it and decides to order a gun from another dealer or distributor. He provides my FFL and asks that the gun be sent to my premises instead of my UPS box. He keeps a watch for it and intercepts it before delivery to me. Now, he has a gun with no 4473, I have no record of the transaction, and I will have to start answering questions to the ATF if the gun is found at a crime scene and starts a trace. It looks to me, agent Larry, like you've deliberately enabled arming terrorists since the mailman could order 1000 AKs. As long as the order gets paid for, all would be well." "Could that really happen?" asked Larry. "I don't know why not. They have everything from my business to order guns and the capability to intercept the shipment". "Thanks for that input. I'll get back to you". I think it was about 3 days later; I got a call from the local postmaster saying I could come pick up my FFL copy. No explanation, no further interaction with agent Larry. I've never had anything but, "thanks for your business" any time since then that I mail a handgun. Since I use a discrete version my business name on the return address i try to make the package not "look like a gun". It would seem to me that attaching the 1508 to the box says, "steal me". Even with this sort of stupidity, I choose to be happy. That will last unless you make me tell my UPS depot story....
