“If that’s true, I hope that can be proven.”
If Corsi was a halfway decent reporter/investigator, he’d be able to prove this in a second. When he heard about the allegedly impending forgery, in enough detail that he knew exactly what was on the document, why didn’t he record these rumors in some verifiable way? Wouldn’t that have been the easiest way to debunk the document (”Look, this document released on X date says exactly what I knew it would say 3 weeks earlier, as shown by this memo dated 3 weeks before X date”)?
I don’t know. That is a valid point.
People would say he was just told what was on the real BC. Knowing what was on a BC ahead of time doesn’t prove whether it is or isn’t genuine.
