OK. A cage that is in a county, or city - that is in a state - as opposed to Federal.
And yes, you ARE correct that federal prisons are better than state prisons. It will be hell every day, where he is going. Nothing like jails or feds. I assume he will be put into a cell, instead of a dormitory, due to his notarity. Although cells offer more privacy, they are psychological torture, with how small they are (living in a closet) and how a cellmate will certainly be required, as no one gets a private cell, unless you’re in solitary confinement (ad seg). Trust me — he’ll lose 50 pounds the first six months alone. And he will age three times faster in every way.
Sounds like you know what you are talking about. I have a close relative who went to Federal prison. It was bad enough.
Well at least in jail, you get out (eventually). In Hell you don't.
