And maybe he does. But what brought him to the attention of BATF is his buying NEW guns from FFLs that could be traced to him. Again, if you are going to walk a tight rope, some one is going to look up and see.
BTW, BATF knew that he had purchased a Lorcin and an Intratec (which he didn't trot out to show the world.) Where did the BATF get that info, if there is no central gun registry?
Maybe he is one of the guys he referred to as buying multiple handguns in week from one FFL, which generates a report to the BATF.
Who knows... If he was operating as an unlicensed dealer or something, I wouldn't expect him to fess up to it on Youtube... lol
