I agree but I think unless it is specifically written into the law to pardon all criminals of that specific crime, they don't get out. I think the theory is that at the time they committed the crime, they knew it was illegal so that shows them to be of questionable character and they need rehabilitation for that. Then you have to consider who gets out. The violent criminals or just the poor schmuck who got caught with an eighth for the the 3rd time or both? I think it becomes complicated and nobody wants to touch it. I also think it's terribly unfair.
