Not at all. We might for example see recidivism drop off after a few convictions. That would be the case if prison could reeducate people.
I'd expect recidivism to be low after a single conviction if the system works. But you can't teach an unwilling student, so frequent fliers will keep coming back.
Exactly, it’s important to remember the overall recidivism rate is much lower than the US’s. Unfortunately I think some amount of crime is inevitable and is ultimately reflective of societal development or lack thereof. When you get to multiple convictions, the cost of letting someone go has to be balanced against the cost of incarcerating them permanently, and the relative harm they would cause over the rest of their life if they simply could not be socialized properly. Maybe we really should be locking them away forever. Maybe we shouldn’t. I don’t think we’re ready to have those discussions yet. Emotion and retribution still drive how we punish people, to a destructive extent. It’s clear we could still go much farther in liberalizing and reforming the penal system before these questions become the most important questions to answer.
