just compensation for unjust imprisonment

questions about our evolving legal system...

what does the state owe for it's mistakes? what about culpability of the prosecuters? what about incompetent defense lawyers? is disbarment enough? payments are being made, so where is the accountability for us taxpayers? and if there is compensation, where does it end?
should we punish juries that get it wrong?

How do they figure the payouts for people who were wrongly convicted?

sorry, I've only got questions on this one. I know it's a half-baked post but I wanted to put something here for my thirsty readers.
