The U.S. military took more than four years to process a Freedom of Information Act request for a copy of the Guantnamo guidelines for censoring prison library material - and censored the guidelines when it processed the request. The paperwork the military released appeared to leave out three pages of the prison's procedure for handling the Quran. The Miami Herald sought the Nov. 27, 2013, document in a Dec. 10, 2013, FOIA request. The U.S. Southern Command apparently released the document, with redactions, on March 21 but didn't put it in the mail for five more days. It arrived at the Herald newsroom, which is next door to Southcom, on Tuesday. The Guantnamo prison is a Law of War detention site run by the Pentagon; left unclear was the U.S. military's law enforcement or prosecution function related to the Detainee Library, which circulates books among 26 of the prison's 41 detainees. Of those 26, only two have been convicted of war crimes. Former CIA captives at the clandestine Camp 7 prison, including those accused of plotting the 9/11 attacks, don't have privileges at the main library but can draw from a different, secret collection. In May 2016, a U.S. Army officer in charge of detainee diversionary programs told reporters that "negative screening criteria" included military topics, extreme graphic violence, nudity, sexuality and extremism. Many of the prison's current detainees were held by the CIA for weeks or years before their transfer to U.S. military custody.
