I am not interested in making ANYONE jump through a hoop, but the federal government / BATFE requires that I enter into my A&D Book the name and license number or name and address of everyone from whom I acquire a firearm in the course of business.
If mbogus, the actual seller / shipper, sends me a firearm to transfer to a buyer and lists his name as 'mbogo', using the address of said mbogo, how can I verify the shipper / seller information he supplied? For all I know, mbogus stole the firearm from mbogo and is selling it for his own ill-gotten gain.
For ME, in MY business, I have decided that any fireram sent to me by a non-verified licensee must be accompanied by a copy of the seller's State ID including signature, along with a signed Bill of Sale from the seller. If the information and the two signatures on the State Issued ID and the Bill of Sale do not match, I will not process the transfer. That is my business practice, not a federal regulation, and any seller who chooses not to comply with that will just have to arrange with the buyer to "find another FFL to handle the transfer". I do not see that requirement as onerous for anyone involved, and it goes at least a small way towards insuring the integrity of the transaction for both the buyer and the seller. I would advise any of my customers to steer clear of a non-licensed seller who was reluctant to provide that information on an interstate firearm sale, whether said seller was mbogo or mbogus.
