So the only thing I know about US prisons is what I have seen on that show on lockdown. If that is anything to go by there is a massive problem! They showed a prison in Arizona where the guys live in tents as there is no room for them in the main part of the prison. It seems every episode shows a prison with a similar situation where a gym or some other building has been turned into a giant cell.
But hey if its run like a buisness why would the people running the show have any reason to change it?
So many runs so little time.
