The problem with that analysis is that it presumes that the only negative consequence to selling in violation of the BGC law is either getting "outed" by a journalist or getting busted by the cops in a sting.
I can think of at least one other negative consequence: The gun you sold in the parking lot is then used in a crime or a suicide and when the cops trace the serial number it comes back to you. If the records show that you possessed the gun after the BGC law went into effect (say you bought the gun in December 2013 and filled out a 4473 with that date) you're going to have some 'splainin' to do.
