I don't think he is an FFDO. An incident like this would have been flashed to all of us in a brief or at least on our messaging system and I have received none nor have any other FFDOs that I have spoken to.
He was definitely operating solo and without legitimate creds. Anyone in the FFDO mission would commit career suicide by pulling a stunt like this, not to mention complete character and professional breakdown. I cannot imagine anyone of my peers acting like this. If he was FFDO we would've head about it long before it appeared on this board.
Until I see or hear real evidence, or facts, this boob is another moron with a fake badge and an identity crisis. Let's not defame the already fragile FFDO mission and status by some off the hip allegations until we know the facts. My bet is he is all of nada and just another chemical imbalance waiting for a real incident.
