A Report on Abu Ghraib at the New Yorker.
When Taguba urged one lieutenant general to look at the photographs, he rebuffed him, saying, “I don’t want to get involved by looking, because what do you do with that information, once you know what they show?”
Several of these images, including one of an Iraqi woman detainee baring her breasts, have since surfaced; others have not. (Taguba’s report noted that photographs and videos were being held by the C.I.D. because of ongoing criminal investigations and their “extremely sensitive nature.”) Taguba said that he saw “a video of a male American soldier in uniform sodomizing a female detainee.” The video was not made public in any of the subsequent court proceedings, nor has there been any public government mention of it
The team spent much of February, 2004, in Iraq. Taguba was overwhelmed by the scale of the wrongdoing. “These were people who were taken off the streets and put in jail—teen-agers and old men and women,” he said. “I kept on asking these questions of the officers I interviewed: ‘You knew what was going on. Why didn’t you do something to stop it?’ ”
If they had spoken, Taguba said, he would have reminded Miller that at Abu Ghraib, unlike at Guantánamo, very few prisoners were affiliated with any terrorist group. Taguba had seen classified documents revealing that there were only “one or two” suspected Al Qaeda prisoners at Abu Ghraib. Most of the detainees had nothing to do with the insurgency. A few of them were common criminals.
The official inquiries consistently provided the public with less information about abuses than outside studies conducted by human-rights groups. In one case, in November, 2004, an Army investigation, by Brigadier General Richard Formica, into the treatment of detainees at Camp Nama, a Special Forces detention center at Baghdad International Airport, concluded that detainees who reported being sodomized or beaten were seeking sympathy and better treatment, and thus were not credible.
(At the hearings)...And, as a result, somebody just sent a secret report to the press, and there they are,” Rumsfeld said.
Taguba, watching the hearings, was appalled. He believed that Rumsfeld’s testimony was simply not true. “The photographs were available to him—if he wanted to see them,” Taguba said. Rumsfeld’s lack of knowledge was hard to credit. Taguba later wondered if perhaps Cambone had the photographs and kept them from Rumsfeld because he was reluctant to give his notoriously difficult boss bad news. But Taguba also recalled thinking, “Rumsfeld is very perceptive and has a mind like a steel trap. There’s no way he’s suffering from C.R.S.—Can’t Remember Shit. He’s trying to acquit himself, and a lot of people are lying to protect themselves.” It distressed Taguba that Rumsfeld was accompanied in his Senate and House appearances by senior military officers who concurred with his denials.
“The whole idea that Rumsfeld projects—‘We’re here to protect the nation from terrorism’—is an oxymoron,” Taguba said. “He and his aides have abused their offices and have no idea of the values and high standards that are expected of them. And they’ve dragged a lot of officers with them.”
The whole thing is very long, but it's worth the trip. Sickening, but worth it.
