Sounds like they are tossing out as a trial ballon the idea that the originals (typed?) were scanned and run through Optical Character Recognition (OCR) software, which coverts the scanned image of text into text. Assuming it was done on a PC with Times New Roman TT fonts, they could argue the output would look like what CBS has in the mystery documents.
All of which is very nice, except there's no way to distinguish between an OCR'ed document and one that was typed last week on a PC!
Unless they have the original docs from the 1970's, it's not believeable.
That doesn't even address the issue regarding the content of the meoes being bogus (Army vs. Air Force terminology, etc.)
Sure. But the funny part is, even if that were true, the memo would still be a forgery which was attempted to be passed off as real. After all, a printout of an OCR-scanned memo would not have Killian's signature on the bottom of it! So whose signature is that? The one who attempted the fraud, by definition.
Thus the "scanned" theory, if true, means that fraud took place. The funny part is that the guy bringing it up doesn't seem to realize it. :-)
