I was talking with some people in real life about a recent situation, and one person said that jail was supposed to rehabilitate people. It's not that I think jail/prison isn't an opportunity to bring down the recidivism rate... but I don't think one should assume that rehabilitation is automatically one of the goals. I could immediately think of several circumstances where the goal was to prevent harm to people, to get offenders off the streets, even if those offenders weren't going to turn their life in a different direction. Anyway, I wondered if maybe I was off-base, and that rehabilitation was an assumption regarding confinement, as opposed to it being tacked on only in certain circumstances. What do you think?
