I don’t believe he’s ever spoken of making a “mistake”. This is what bothers me and why I could not issue out a pardon to the guy. If he were merely brainwashed...and he came to realize the problems of Islam...then it might be to our advantage to let him out to explain this issue to the public. Strangely enough....he never says a negative word about Islam.
With that said, even if he were speaking against Islam, I say keep him right where he is until he finishes his sentence unless Afghanistan wants to try him. We have no way of knowing if he has truly changed or is just trying to get out.
