The fact you have gone into spin defense mode for Chris shows how wrong he was, and how bad this looks.
He should just say, "Looks like I was wrong" and "Stop jim, your embarassing me further" and just move on.
This isn't a court of law where you can claim a technicality that he never said it was "impossible". He argued strongly against the idea that it could be done, and even offered it as the reason that Brandon hadn't acted yet. He also doubled down by saying that nobody who is advocating it can actually explain how they go about doing it. This isn't a court of law. It is a court of opinions. Everyone sees.
