People are scared when it comes to firearms and don't really know what they need to sell one legally. When I am asked for one I will politely try to explain why they are not legal documents unless they are stamped by a notary and how in the state of Ga. they are not required. I was contacted and questioned by GBI agent on a pistol that I sold years before then and I promise the conversation was short. He did his homework long before he called me and the only questions I got was... Do I own it? Who did I sell it to? When I told him that I sold several years ago at a gunshow to an individual but I did not keep records of who it was but I always ask for a Ga. DL to prove residence. He said thank you for your time and that was the last I ever heard from him.
I have read just about all these threads pertaining to B.O.S. I have a feeling this is how most interactions after the fact would go. They are looking to solve a crime, not falsely accuse you of something. If you use PM's to communicate the deal before meeting, why would you need a piece of paper with someone's personal info that could possibly be lost or stolen?
