Don't be disappointed. I guessed he was going to do this, and for good reason. His options were to either, live a life in fear, worrying that one day he would be caught, or, to basically give him self up, and elect for a Jury trial. Jury nullification is one os the most powerful tools available to the average, non-rich american. If he goes through the trial and gets acquited (which only takes 1 juror), then hes a free man, a folk hero, and he sets the precident that killing rich murderers isn't an automatic crime.
What he's doing is the smartest available option, please donate to his legal defense fund.
