Well you don't have anything to wipe your ass with.I just bought a 22 pistol 2 days ago. I showed my CHL and he showed me his FBI identification. We both felt good about the deal. No BOS needed. Some of my best buys have been from LE.
I was across from a plainsclothe LE at a gas pump. While we were filling out tanks we got to talking about 1911's as that was what he was carrying. He said he was looking for a 5" Kimber. I told him I had one I wanted to sell. We exchanged cards and a week later he called me. We met at the same gas station and the deal was made. I also typed up a BOS that he signed and I provided one for him I signed.
There wasn't any surprise, scoffing or pontificating about it not being needed.
