That's new, at least new to me. Source for this?
I am giving this from memory, but I recall ‘Ron Polarik’ stating that when he called the vital records dept in Hawaii as he was working on examining the Internet CoLB material and they stated that no request for a CoLB was filed or answered for the date supposedly stamped upon the reverse side of the Internet forgery. The forgery shows June 2007 in the stamp on the back, immediately confirming for Polarik that the document he was examining was not genuine. Subsequently, a retired FBI documents expert—testimony in the Keyes suit in California—has also confirmed that the thing touted as a valid CoLB is no such thing. Her sworn testimony is ,I think, still available ont eh Internet.
