Lately I've been reading up a lot about prisons in America. I'm interested in the prison industrial complex and the pecking order in prison. I do not like reading books written by a know-it-all with a degree in criminology, I'd much rather hear stories directly from people who have actually been incarcerated and understand how the system works.

How corrupt is the system? Do guards frequently abuse prisoners? Are prison gangs rampant and if so, do they act as a pseudo-government for the other inmates?

Any info would be much appreciated

Cheers.
