on the issue of forbidding private prison management that I know of. Some legislation has been introduced that is supported by AFSCME (American Federation of State County and Municipal Employees). Go to their page (http://www.afscme.org/) to find it (legislative Action, Public Safety Act). I suspect it will die a natural death. (BTW, these union guys have been frequent posters here.)
Ohio also consider legislation against housing out of state prisoners. Their own attorney general told them not to bother.
