I don't think I agree with this, but it has made me think about the problem differently. We don't send somebody to the hospital for "30 days", or "1 year". We don't do it when putting somebody under the care of a psychiatrist either. We deal with the patient until they're recovered. Perhaps this should be the approach we take with prisoners. They're in prison until a professional determines they're rehabilitated and ready to reintegrate back into the rest of society. With—potentially—minimum and maximum durations to ensure some safety rails on the system. I have to admit I don't know what this looks like, and I don't mean to gloss over the fact that there are incredibly difficult questions this raises that don't have good answers (what does it mean for a murderer to be "rehabilitated"?), but I do wonder if at least considering the problem from this perspective might prove helpful.
