Gleick - Fakegate links

This is Heartland's web site about the Gleick / DeSmogBlog / Fakegate scandal:
http://fakegate.org/

This is a 57-page slide presentation (with some redactions) produced by Heartland's legal counsel, Jones Day. It is entitled, "Criminal Referral of Dr. Peter H. Gleick Talking Points." It was presented to the U.S. Attorney's Office for the Northern District of Illinois, and asked that Gleick be prosecuted for his crimes. The U.S. Attorney, a Democrat, did not prosecute Gleick:

On Feb. 16, 2012 Mosher recognized Gleick as the probable forger, which led to his identification as the source of the documents:
