I'm cynical about it and wonder how truthful it would be TBH. All the time he was locked up, his father protested his innocence long and loudly so he either was truly innocent and has a damn good explanation in his book as to why he was where he was when he was arrested OR he truly was part of it all and in which case he can hardly admit it in his book kwim? And I can't see him being allowed to talk about what happened inside because I imagine there would be security issues and stuff like that? The book might shed more light on that though and it would probably still be an interesting read and enough to make up your mind either way.
