One photograph showed a man lying dead in the dirt with blood coming out of his head. Another showed a naked man hanging from a bed by his knees. Another prisoner is shown covered in feces. Naked men are also shown in sexually humiliating positions. Prisoners were photographed wearing hoods. Men were also photographed showing what appears to be burn and torture marks. And the outcry over the photos may only intensify. Earlier today Salon.com published even more photographs from Abu Ghraib. The online publication obtained files and other electronic documents from an internal Army investigation. The material includes more than 1,000 photographs, videos and supporting documents. According to Salon.com some of the documents refer to CIA personnel as interrogators of prisoners at Abu Ghraib. To date, no CIA officers have been prosecuted for any crimes that occurred within the prison, despite the death of at least one Iraqi during a CIA interrogation there. On Wednesday, the American Civil Liberties Union, Amnesty International and other groups called for a truly independent investigation to look at all levels of the military chain of command, as well as involvement from other government agencies like the CIA and private military contractors who have been implicated in abuses.
