You're right, wardaddy. Defendants are rarely shackled in front of a jury, and until he was convicted, he was still presumed innocent. Nowadays, they use stun belts, although it looks like this guy was supposed to be wearing one and wasn't.
And I don't want to think about the scum that killed Polly Klaas. But I will never forget what he said at sentencing. How Marc Klaas restrained himself is beyond me. I would not have been able to.
