Last week Deputy Attorney General Sally Q. Yates seemingly turned the criminal justice world upside down. Her tool? A two-page memo to the acting head of the Bureau of Prisons that laid the groundwork for cutting off relations between the federal government and private prison operators. Citing the private facilities for excessive levels of violence, lack of “rehabilitative” services and failure to deliver on promised cost cutting, she directed the BOP head to “reduce” with the aim of “ultimately ending” federal contracts with private prisons. In the immediate future, BOP is either to “decline to renew” or “substantially reduce” the “scope” of each private prison contract when it ends.
