threw this theory out here a few days ago, it still seems plausible to me:
Using the time line with Burkett, his INTERNET posts, Cleland, Mapes in Texas, sending of the faxes on 9/2 receipt on 9/3 and the broadcast on 9/8
Wouldn't it be funny if Burkett gave the Kerry campaign the info(as in his internet post) they made the docs (he thinking they could get a real forger to do it better than he could and he could deny he forged them) and Dems sent them back to him, then DNC contacts CBS getting them (CBS and Burkett) together and then Burkett faxes them to CBS after he first gets them from Dems...
It fits with all the mistakes and using a word processor instead of a typewriter, maybe a 30 year old flunky or novice forger..Burkett would have known better the forms and abbreviations etc by the way I wonder if a dem did forge it and used one of Kerry's letters as a format-center justified signature-like this one at their site.(below link) Also look at the letterhead, the date year is 4 numbers unlike Air Force 2 numbers, and billet is a term used in the Navy, possibly not in the Air Force.
It is plausible Burkett got the docs from the dems and noticed errors but CBS was pushing him for time(why didn't he give them to Mapes and Rather the first meeting if he had them all the time?) so he faxed them anyway due to time constaints.
Compare this document from Kerry's site to the two posted at WP, one real and one forged and notice the mentioned differences, which makes me think someone from Kerry's camp had a hand in the forgery.
