"Rather says [Memogate source] was 'unimpeachable'"
Bill Clinton? Remember, Rather said that Clinton was an honest man.
Recalling the FBI file scandal of Bill and Hillary Clinton, maybe the Clintons also accumulated military service records of political figures for future use?
Using some lower level political associate as a cut-out for deniability purposes, Clintons can leak military records to advance their purposes.
Since the files here are forged, I doubt that the Clintons were involved. However, I'll bet they do have military files as well as FBI/security clearance files on various political figures and will use them if needed. Remember that the Clintons had their man at the Pentagon leak info from Linda Trippe's DOD file.
Actually Marcel Matley, who "authenticated" the signature on one of the CBS forged documents, also "authenticated" the "suicide" note of Vince Foster for the Clintons even though three REAL and QUALIFIED experts said the opposite.
The MSM's control of information flow was much stronger eleven years ago than it is now, and thank God for that.
