"I don't know about Gregory yet, but it looks like Fitzy is gonna have to indict either John Dickerson of Ari Fleischer.."
Have you already forgotten about Ari's plea agreement? Just in case you have, it granted him immunity from prosecution.
True, but the plea bargain doesn't cover perjury on the witness stand during the trial. He says he told Dickerson and Dickerson says 'no way'--so since faulty memories can't happen (according to fitzy) then we have a liar.
