How has societal viewpoints concerning incarceration and probation influenced human services over the past three centuries?

I believe that it has changed drastically. The purpose of prisons was to help offenders straighten their lives and reintegrate to society. That is why it was based around three models, Custodial, Rehabilitation, and Reintegration. Probation was a way to help the young offenders by placing them under supervision but it also changed to help rehabilitate regular inmates and reduce crowding in prison.

I hope it helps, Regards.
