He knows who the Forger is. He just can’t prove it. Trying to out the Forger is not going to work. Presenting “Earth Shattering” evidence would work. This evidence was claimed a few months ago. Nothing since.
This evidence is not for a Grand Jury. It is for the Public.
Throw it out there. Nothing to lose by trying. It sure won’t hurt credibility issues because right now there is NONE.
