So what were the pages and pages and pages and pages of redacted documents all about?
Just what witnesses have said and a proffer that the SP wanted to verify that the reporters would confirm or lie?
I don't think so.
I'm sure it started out as a genuine investigation into the merits of the allegations. He might even still be hoping to string up someone for leaking the info. But failing that, you can be certain that he'll settle for perjury, if he can prove it.
There were a lot of witnesses who testified already. Now he has some reporters who may or may not be able to contradict those stories.
