PLaw,
No, I'm not saying that at all. Everyone is entitled to a fair trial! If, in any case, with any one, it turns out the trial wasn't "fair", then by all means he should be retried.
I'm simply saying that Moussaoui "said" he now believes he can get a fair trial. He is entitled to it, and I can only assume he had one. I am asking/questioning the legitimate reasons for asking for an appeal. Can you simply say you want to change your plea for guilty to not guilty and get an appeal?
