Yeah, heard about this, as much as I hate to say the the Governator was right, it wasn't his place to second-guess the court system, particuarly after the amount of hearings and appeals there have been over this man.
I'm not a fan of the Death sentence anyway, it could well be that the State of California has indeed just murdered an innocent man, I have no way of knowing, but it is up to the courts to make that decision not Arnie, and, quite frankly, if it does turn out that he was innocent, then that should land on the courts, not Arnie, though I don't doubt it would land on him.
