The Department of Defense partially complied with a Freedom of Information Act request to release names and transcripts from the captives ' Combatant Status Review Tribunal s and Administrative Review Board hearings , on March 3 , 2006 . The Department of Defense released 59 portable document format files , containing transcripts , memos , and other documents . Three of the PDF files contained 121 Summary of Evidence memos . In early September 2007 The DoD released fourteen pdf files that contained all 464 Summary of Evidence memos prepared for the first annual Board hearings , and ten files that contained all 333 Summary of Evidence memos prepared for the second annual Board hearings . Discrepancies in the spelling of the captives ' names . The names of the captives were redacted from all the transcripts . Their transcripts were identified only by their ID numbers . The captives ' Summary of Evidence memos , on the other hand , had their ID numbers redacted , but the captives ' names were in the clear . On April 20 , 2006 the Department of Defense released a list of the names , nationalities , and ID numbers of the 558 captive whose status double - checked by a Combatant Status Review Tribunal . The release of a list of names , and ID numbers allowed the transcripts to be correlated with the captives ' names .

The memos all contained the same five numbered paragraphs : Both the factors favoring continued detention , and the factors favoring release or transfer were followed by lists of allegations , or " factors " . Transfer , in this context , means repatriation to the custody of the authorities in their native country . The allegations , or " factors " , the favored continued detention were always further categorized into sub - headings , like : " Intent " , " Commitment " , " Connections " , " Associations " , " Training " , and " Other Relevant Data " . The factors under each subheading were always separately numbered , except intermittently , if the subheading only had a single factor . Some of the allegations , or factors , did not concern the activities or associations of the captives , before their capture . The factors favoring release were not numbered . This list was almost always quite brief , and , in some instances , merely said : " not applicable " . One common factor favoring release was that the captive had claimed he had no advance knowledge of the plans for Al Qaeda ' s attacks on the USA on September 11 , 2001 .
