Thats the point. You cannot just assign a sentence and presume rehabilitation at the other side. Crimes along the entire violence spectrum that require removal from society all require case by case consideration of when, if ever, the criminal is suitable to reenter society. A lot of them never should, that never repent and would always be a threat to others. But then you have those that rot in jail for decades after being completely rehabilitated by policies like mandatory minimums and extended sentencing like mentioned in this article waste their lives and our tax dollars on something that a board of active professional psychoanalyists should be able to see is a shut case. It is easy to deceive an inefficient, corrupt, or lazy system when given per-case inspective authority. But it is not easy in the presence of a rigored well implemented system. Rather than try to simplify criminal justice to sentencing based on crime committed with fixed sentences taken from a textbook, we should appeal to reach the global maxima of justice, which includes curtailing the injustice of keeping those no longer dangerous behind bars perpetually.
