the judge won't allow that. the only real chance he has is either an insanity plea (and then he'll be locked in a prison for the insane which is worse than a regular prison), or basically just talk about what a good boy he is and he's got such a bright future and he'd never do nuthin' to ever jeopardize all that, and hope some retarded female takes sympathy on him and hangs the jury. at which point he'll get retried and get the chair.
