I gave it a search. I even went to their website but couldn’t figure out how to look from there. I believe it was recorded. I seem to recall having found it at one time shortly after the event, which was probably around 2010. The guy was an amazing speaker. Logical. Persuasive. And the way he disarmed a potentially dangerous group was incredible to watch.

Thanks for looking. I did a few searches also but couldn’t find it. Maybe it will turn up someday.
