Quoting Mrs.Pinkman:" It really depends on what they're in jail for. If they're in for things like petty theft then all the ... [snip!] ... citizens. But if they're in jail for rape, molestation, murder, etc.. then they don't deserve to get out of jail ever."
My friend's murderers got 80+ years for murdering him. They were already in their 30s at the time. Even if you knock two years off their sentence, they're going to die in there.
So I just sort of see it as... More power to ya if you want to try to reduce your sentence. It's not going to make much of a difference for these lifers who will die in prison before their sentences are up, reduced or not.
