Furthermore if prior to or during the face to face, (always in a public place) led me to believe anything was hinky, it'd be a no deal, regardless if i was buying or selling. I'd also make note of a vehicle discription and plate number and any other pertenant information.
The problem with doing any sort of paperwork on scene is that these transactions always seem to have one or both parties trying to get done fast and leave. As to intent, I tell the other person that I like to have this information to check legality, especially in this political climate. Should everything come back okay, I shred the info.
The wonderful thing about our rights as they are currently defined is that no one has to provide anything they don't wish to and I don't have to release my cash for a gun I can't check out. When it feels wrong, for either side, don't do it. I just try to CYA to the best of my ability and not wind up paying for stolen property.
