How humane are prisons in the U.S.? And what is their purpose – to punish or to rehabilitate? This is part one of a two-part series that dives into the prison system, what it looks like from the inside, how it destroys the lives of black and brown folks who have been overpoliced and tossed into the prison system for decades, and the work being done to counteract that system. After a field trip to a California state prison, Jim Underdown spoke to Steve Hill about his frank experiences as a prison security guard and what he thinks about the future of the prison system. Steve Hill is an atheist activist, Comedian politician, a former marine, and former prison security guard who worked in the California penal system as a prison guard for ten years.
