The guy you are talking about is Sheriff Joe Arpario. He is the Sheriff of Maricopa County Arizona.
He is over the county jail...Not the same as a prision. A jail merely holds people convicted of misdermeanors and people waiting to go to trial. I've seen parts of his jail and talked to several people that have been locked up there. IMHO his jail, while saving the taxpayer money, is borderline inhumane.
Jails and prisions have totally different sets of rules. Long term prision inmates have many more rights than people housed in county jails. If Sheriff Arpario was running a prision in the manner he runs his jail he would soon be out of a job and the state would be overrun with lawsuits.
