Corrections Corporation of America (CCA) is the largest for-profit, prison detention center operator. They make a profit, off of inmates. There has been much controversy over the governments use of private prisons, including a recent story where 8 inmates filed a lawsuit against CCA for letting gangs control their Idaho Correctional Center, in an effort to save money.
In a related story, the owners of two private, for-profit juvenile facilities, in Pennsylvania, were giving kickbacks to a judge, Mark Ciavarella, for sentencing children to extended stays in juvenile detention for offenses as minimal as mocking a principal on Myspace or trespassing in a vacant building. This scandal became known as "kids-for-cash".
It now looks as if CCA will begin hunting children directly at school. It's a great business model, if you're a psychopath.
