As I understand it, this is a case of whether a re-examination or re-trial can be compelled based on future factual revelation, even if the trial was free from error.

I had always assumed, of course. It only makes sense that you never, ever want to punish the innocent and should always err on the side of being sure; particularly in the case of life- and death sentences.

If this man winds up being shown innocent and is still to be executed, it will be an absolute miscarriage of human justice and an indictment of our entire legal system.

Even if extraordinary powers are exercised to keep the State of Georgia from executing this particular man (and I can only hope they would be), the simple fact that our system would otherwise allow it to happen absent special dispensation is abhorrent to everything our nation supposedly stands for.
