Under Hawai'i's Uniform Information Practices Act, they'd probably have to release their settlement info.  There have been conflicting decisions by the Office of Information Practices on whether the Hawaiian (In)Humane Society falls under the Act, but those are just opinions and they are conflicting as I recall.  So CCA is fulfilling a governmental function, and the information is the same as that state run prisons keep and would have to disclose.  Maybe the Civil Beat Law Center would bring it. :)

If that doesn't work, the next people who sue them may receive the information during the discovery process, and would be perfectly free to release it prior to settlement.

Also, don't forget to delve into the federal prison and detention center...
