Noted: It’s dangerous to give guards authority over someone’s length of sentence, especially in a privatized prison. A study out of the University of Wisconsin Business School last summer found that guards in private prisons write twice as many disciplinary reports than their public prison counterparts because these bad report cards cause the parole board to deny inmates who have documented history of behavioral problems. The end result is that the inmate serves more time. And earns more money for her jailer. Prisons have less to do with courtrooms than they do casinos – the house always wins.
