I oppose most prison sentences, but not strictly prisons. I'm curious what your alternative is?

For clarity, I'm for rehabilitation and not retribution -- it gains us nothing. When it comes to drug crimes and youthful offenders, community service and rehab seem like far better things than X days/months/years in jail with a grabbag of offenders running the gamut from arsony to grand theft to smoking a joint. And while I think the purpose of imprisoning them should be to offer rehabilitation, would you not imprison murderers or would you put them in mental health institutions rather than "prisons"?

It's a big topic: http://en.wikipedia.org/wiki/Prison_abolition_movement

Thanks for the link. That's actually a pretty good enumeration of my issues with the current system in the US. I don't think I'd go so far as to say eliminate all prisons, the sorts of prisons we have today are not the sort that we should be using.
