Last year, the ACLU reached a settlement with CCA over its deplorable operation (or lack thereof) of the Idaho Correctional Center, which was so plagued with violence and assaults that it had been dubbed "gladiator school" by the prisoners. The lawsuit had sought up to $150 million in damages, but a settlement was reached that was likely substantially lower (and which allowed CCA to avoid admitting responsibility). After the settlement, the AP petitioned the court to have the settlement documents de-classified, so that the public could get an idea of the terms of the agreement. Such a move could have given the public a better understanding of just how shitty this CCA prison was, and still is; in fact, it was still the most violent prison in the state, even after the lawsuit settled!
But apparently the judge doesn't want the people of Idaho to have any real oversight of the private prison that's taking millions of taxpayer dollars every year to provide such substandard treatment, because he refused to unseal the settlement. His basic reasoning was that he feared releasing the documents could discourage a company like CCA from seeking settlements in the future. Which would be GREAT, because then they could actually have to take some responsibility for the thousands of instances of abuse and negligence that have taken place in the prisons they're paid billions of dollars to operate.
