Im a Corrections Officer. AMA
I work in a state prison. Ive worked in several facilities in my state and in a number of different types of housing units. Im on graves right now and its pretty slow, so I'll answer questions for the next few hours if you like.
The American prison system is not at all homogenous and I can only answer from my own personal observations and experience. Your experience may vary.
Thank you.
Edit: Time to clock out and go home. Thank you everyone. This was fun.
