If the e-mails contain exactly that which Corsi claims then it's a different story.
I hope the emails have some “I am the one they have been waiting for.” in them. He’s such a hitleresque freak. It goes to show ya that sometimes having a dysfunctional childhood can DOOM the child. His poor daughters were babysat by Ayers and his wife. I wouldn’t trust my kids w/domestic terrorists.
I'm still reading the thread, so maybe this has already been mentioned. Print outs of emails don't consitute evidence, nor would even the hard drive on which the original emails are purported to exist. Corsi would need to have in his hands the actual computer which is purported to have received the emails. That, at least, would substantiate the legitimacy of the actual emails having been received as reported and not tampered with. It would require some sort of computer forensics investigator to authenticate. From there, we'd only have proof that the emails themselves are legitimate, but we'd still lack proof of the sender (although, with enough time and justification, perhaps search warrants could be obtained). There are certainly other people on FR who would know more about this than I do, but this is my understanding based on some passing experiences.
I'm confused by Corsi's story of having emails. I hope he has much more than that, and something(s) that are irrefutable.
