If there's one image that could hasten an investigation, it would be this:
At least one picture shows an American soldier apparently raping a female prisoner while another is said to show a male translator raping a male detainee.
Further photographs are said to depict sexual assaults on prisoners with objects including a truncheon, wire and a phosphorescent tube.
Another apparently shows a female prisoner having her clothing forcibly removed to expose her breasts.
If true, this would seem to call into question Obama's definition of the word "sensational." It should also be acknowledged that pictures this vulgar wouldn't play well in the Middle East. But that doesn't excuse for hiding evidence of a crime being committed. More here, including some brutal images that have already been released.
