So let me get this straight -
1. You have the most concrete gathering of elite at any one place in time during the world and your security consists of some chicken wire + trees. Backing up this state of the art security you have sheriffs deputies and secret service. Odd combination, no?
2. Conveniently, none of the "numerous encounters" between the film crew / security was captured on tape.
3. Oddly enough after so many run ins with the internal security, they're still allowed to go on their merry little way. No IR detectors or scrambling devices of any sort to interfere with audio/video recording.
4. You are going into one of the most secret places in the world to film a documentary, of which the main event is occurring at night, yet you bring one hour tapes and a hidden camera with no night vision.
5. An elitist secret organization with no secret codewords or catchphrases to root out outsiders.
Sorry Mr. cooky christian, not much of a documentary you got there.
They probably knew he was coming a week in advance and flew down some actors for the ceremony. When he left, the real sacrificing and orgies began
Thats pretty much the only thing I can think of - that this so called organization engages in such bizarre shit that anyone who comes forward with it would be thrown into the nut-house. Security with no security 
I can never be free, because the shackles I wear can't be touched or be seen.
