One thing I've noticed about the authentic documents versus the forgeries: After enlarging the authentic documents, one cannot see the information hidden by the black out. Not true of the forgeries (re: the address).
This brings up a really interesting point. Try this one at home, kids!
Sign your name, print, or type something, whatever, on a sheet of paper. Take a black magic marker and line through it. Then make a photocopy of that document, or, to be more true to form, go through fifteen generations of copying. Hold the two up to the light. On the original, it's VERY easy to see the original information you marked out. On the final copy, though, it's impossible, because the photocopier only picks up the black mark, not the underlying writing.
This to me is incredibly damning evidence against CBS. They can't produce original documents because there aren't any.
They did up a MS Word document, photocopied it fifteen or twenty times, and THEN blacked out the pertinent information. Otherwise, the info would NOT be visible through the blackout. It's physically impossible.
