Criminal investigators tried to stop abuses at Gitmo

In a 2-part series for MSNBC.com, Bill Dedman details the investigations into detainee abuses at Guantanamo. "[F]ormer leaders of the Defense Department's Criminal Investigation Task Force said they repeatedly warned senior Pentagon officials beginning in early 2002 that the harsh interrogation techniques used by a separate intelligence team would not produce reliable information, could constitute war crimes, and would embarrass the nation when they became public knowledge." Despite these warnings against aggressive interrogation techniques, such abuses continued at Gitmo. Techniques used on Mohammed al-Qahtani (the alleged "20th hijacker") could make him "unprosecutable".
