Combetta will be having much more than a few sleepless nights. He is now a -major- threat to HRC’s political ambitions and even her freedom. If he speaks, they go down. The Clinton machine will be contemplating another wet-work solution and Combetta has to know it. His advisors would do well to make it clear to him that he is in mortal peril. His only safety is in taking them down before they get to him.
While I don’t disagree with you on Combetta or the Clintonistas enforcing omerta as zealously as La Cosa Nostra, his dogged 5th Amendment pleas are the equivalent of fireworks and sirens notifying Camp Hill that he doesn’t want to become a target.
