Someone pointed out that forging a military doc is a crime that has its own category.
I think the cops would have every reason to bust down the doors at CBS, IF someone would, as a private citizen complain to them (either NYC cops or FBI in NYC). They certainly have enough for probable cause.
Finding a non-liberal judge to approve the warrant would be the hard part......
I'll bet the FBI itself has a database of old typewriter fonts. I would think the FBI could determine in a matter of minutes whether or not there was cause to believe these documents were forged (btw, I haven't been able to access those CBS documents for hours . . . It appears CBS has pulled them, or its server is swamped . . . If the former, imo, that is an acknowledgement that this whole thing is a fraud).
