I listened to it. There is no way to tell from listening to the recording, what, if anything extraneous to the microphone itself, is causing the sound. For that matter, there is no way to even verify the origin of the recording, unless someone did some actual scientific study to identify the various wavelengths, etc. The suggestible, visual portrayal by actors certainly lends itself to suspicion of the speakers' intent. I did find it interesting that the speaker employed a little "thought modification" technique that Wierwille was fond of. ("If I tell you what I know about this, you may not believe me." or as Wierwille said, "It'll blow your mind!") By doing this, he creates a desire to WANT to believe. Wierwille was quite adept at this ploy and used it frequently in the foundational and advanced classes. Tape of no tape, this guy is clearly cut from the same bolt of cloth as VP.
"Ladies and gentlemen, it's a DISGRACE to have been in this fellowship of gnashing teeth this evening!!" :P
