This is a reproduction of an important official FBI report about allegations of detainee mistreatment at the Joint Task Force Guantanamo Bay Detention Facility (JTF-GTMO, GITMO), the Abu Ghraib prison, and War on Terror enemy combatants. The report found that after FBI agents in GTMO and other military zones were confronted with interrogators from other agencies who used more aggressive interrogation techniques than the techniques that the FBI had successfully employed for many years, the FBI decided that it would not participate in joint interrogations of detainees with other agencies in which techniques not allowed by the FBI were used. The review determined that the vast majority of FBI agents complied with FBI interview policies and separated themselves from interrogators who used non-FBI techniques. In a few instances, FBI agents used or participated in interrogations during which techniques were used that would not normally be permitted in the United States. These incidents were infrequent and were sometimes related to the unfamiliar circumstances agents encountered in the military zones. They in no way resembled the incidents of detainee mistreatment that occurred at Abu Ghraib.
