I have been labouring to read through this "agent's" (he hasn't explained how he became an agent so far) site and there are a lot of things that are giving me pause (ignoring the atrocious use of the English language, apparently agents don't have to learn how to write). Just a few notes on my first scan through.
First, he claims it was he who suggested the 'box knife" idea, in response to a question from a Sergeant on what types of weapons to use.
Second, he notes letters of support from Canadian officials. Carolyn Parrish may be known to some Americans. She is the Liberal MP backbencher who called Bush a moron (as well as numerous other anti-American tantrums) and was expelled from the liberal caucus. she did not run for re-election. Minster of Defense McCallum's letter is a standard form letter. The others are e-mails.
Third, there is simply no documentation here. Absolutely nothing that would serve as an independent confirmation of any of his assertions.
Fourth, I don't find anything that indicates he supports a CT theory beyond the LIHOP idea, suggesting incompetence, not conspiracy.
Fifth, the polygraph lends credence to his belief in his claims, not necessarily the claims themselves. Most christians would pass a polygraph on the existence of god, but this would hardly serve as evidence of anything but their belief.
I think i'll go try and some mention of this study, should be some sort of congressional record on it.
