Wow, it appears my recent postings have again raised up a sore subject. Believe me, I understand it.
So, I am about to 'take one for the team' here by way of explanation. I will keep it relatively brief.
Certainly, there was a bit more to the story, which at this time I'll keep personal so far as the board posting goes.
I sold a gun to Joe-Bloe on-the-street. Had valid Az D/L. Turns out that Joe was a felon, and said gat was recovered surrounding some (unknown) bad ju-ju. Local po-po engaged our favorite Feds to trace it. Those favorite Feds invited me to a voluntary meeting for some explanatory, and exploratory, questioning. Let's just say that 90mins later, I had quite an education on their perspective. I also voluntarily signed some documents you may have heard about elsewhere.

As to the buyer having a permit, the senior agent pointed out to me it only means said buyer passed a background check ONCE, in the past. (Yeah, yeah, I know....permit holders don't get b/c'ed again at each sale...but I wasn't about to be a smartass and point that out.). Suffice it to say, anything I sell going forward MUST be done VIA AN FFL.
At least at this time, I won't be answering any follow-up questions in the post.
