CHINO, CA - DECEMBER 10: An inmate at Chino State Prison reads a book on his bunk bed as a California Department of Corrections officer looks on in a gymnasium that was modified to house prisoners on December 10, 2010 in Chino, California. The U.S. Supreme Court is preparing to hear arguments to appeal a federal court's ruling last year that the California state prison system would have to release 40,000 prisoners to cope with overcrowding so severe that it violated their human rights. More than 144,000 inmates are currently incarcerated in prisons that were designed to hold about 80,000. (Photo by Kevork Djansezian/Getty Images)
