I'm still curious as to how a law abiding citizens finger prints show up on a gun that he/she sold? That gun may have passed through several people's hands and yet the only prints on it are from the law abiding citizen of whom the authorities have no finger print records? I'm sorry, I'm just not buying that argument, especially if that gun has moved from one state to another.
That being said, I will never do a private sale to someone I don't personally know, and I will (99.9% sure on this) never buy a gun from someone I don't personally know. I don't own guns in order to sell them. If I do want to get rid of a gun I just take it to my local dealer and sell it to them, then they can do whatever they want with it.
lol
I'm a law abiding citizen with no arrests or anything resembling a criminal record but I've had my fingerprints taken at least a half dozen times, several of which were electronic.
For example...when I got carry licenses (multiple states) I was finger printed.
