Your suspicion won’t happen, that’s a fact. This terrorist will never be set free.
I hope you're right. I'd prefer to see him dead, personally, but I honestly think the current government is going to try to protect him at all costs and if he goes to jail, it's not going to be for long. I think that if he does come to trial they'll probably just deport him back to Russia and hope the Russians will deal with him.
Anyway, they won. Obama is already releasing more terrorists from Guantanamo, I suppose in request to the demands of the Boston bombers.
