[JURIST] Former Army Sgt. Erik Saar, who served as a Guantanamo Bay [official website; JURIST news archive] translator, told CBS's 60 Minutes [news website] that prisoner interrogations were staged to give visiting congressmen, senators and generals the impression that valuable intelligence information was being gathered from detainees on a regular basis. The interview will be broadcast Sunday on CBS. Saar, who spent six months at the camp, said he believes only a few dozen of the 600 detainees being held at the camp were terrorists and that very little information has been obtained from them. Saar also claims detainees were treated in sadistic ways. Saar talked about an incident where a female officer smeared red ink on a devout Muslim detainee's face saying it was her menstrual blood. FBI agents stationed at Guantanamo Bay also have reportedly written classified e-mails to FBI [official website] headquarters saying detainees were being physically mistreated during interrogations.
