Yes, and the mandatory appeals are part of the execution process. You would rather just execute people on a whim? What if it was you? When you're taking someone's life, it is best to be as sure as possible the verdict is correct. I don't understand this medieval thinking of trial and execute immediately. I'd like to think we've advanced as a species since then and would like to think we'll eventually move past the ultimate punishment and no longer see it as within our values. But, until then, we should be most certain the verdict is correct.
