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"?
We have higher incarceration rates than China, and even with their massive population we have more people in prison than China does.
