Prison reform has been a subject of debate for many years now, and there has been a lot of discussion, especially in the past year or so, about what role prison is really supposed to fill. Is it punishment? Disincentive? Reform tool? Protection for society? These debates are not new; similar conversations have been occurring at least as far back as the days of Mesopotamia. In a way, it's probably a problem and a debate that comes along with the existence of society - wherever there is society, there will be those who do not obey its strictures (for whatever reason).
