Sommario/riassunto

Prison, Inc. provides a first-hand account of life behind bars in a controversial new type of prison facility: the private prison. These for-profit prisons are becoming increasingly popular as state budgets get tighter. Yet as privatization is seen as a necessary and cost-saving measure, not much is known about how these facilities are run and whether or not they can effectively watch over this difficult and dangerous population. For the first time, Prison, Inc. provides a look inside one of these private prisons as told through the eyes of an actual inmate, K.C. Carceral who has been in the prison system for over twenty years.
