I wonder how much time and money is saved by plea deals. No plea deals or minimal plea deals would be an incentive to go to trial even if the evidence is overwhelming as you have nothing to lose and everything to gain. I think you see this in high profile murder cases because the plea deal is usually life in prison, which is not much of a bargain for most people so they might a well roll the dice like OJ did and hope the prosecution screws up. I think they're drastically different from the trial punishment for a reason.
