I think Moore is lying. (ie. liar, braggart, openly dishonest, deceptive, of low moral character).
I believe the date of manufacture of these forgeries happend well after Farenlies 911 was released; otherwise I have no doubt whatsoever Moore would have included these documents.
Moore has been tagged with over 50 lies, deceptions and misrepresentations in his 'work', adding another lie, deception or forgery would have not mattered to him in any way, shape or form.
Funny that Moore is telling us this now. Why not three or four weeks ago, when the story first broke? Could it possibly have anything to do with the upcoming DVD release of "Fattyass 911 Lbs."? Hmmmmm... Mabye Moore is a Capitalist after all.
