I don't have a video or audio recording of a seminar, but have been very recently. When you enter the room each and every time, you are separated from your belongings. The only way to do it would be on your person. It is a feasible plan, but if you just want to know anything specific, then ask me. I am not sure what you would hear that would enable you to "expose" them, as anything other than a bunch of kooks. There is not a lot that goes on that is even remotely interesting. Just lots of double talk and program speak and motivational hoo-ha. I think the real answer would to get a recording of the children's seminars. From what I have been told, that's where the true story lies.
