You called it. Hell I'm glad you're right. Now the criminal case can proceed.
The big question is if Martin is psychologically and physically prepared for what's about to happen next. Is he going to delude himself or will he take it on head first?
I can only hope he reads this thread and decides to cooperate, take the offer, develop then admit remorse (not for himself), then start to move forward with the steps to get this concluded. He may do some easy time. If he can see the light and just go through the system, cooperatively, he's young enough to recover if he simply goes straight from here forward. I can't see he has any other option - Foreign Legion?
