Take the case of Mohamadou Ould Slahi, a detainee who Marine Corps prosecutor Lieutenant Colonel Stuart Couch concluded had “the most blood on his hands”,
Slahi, Couch learned, was horribly mistreated. Effeminate and childless, he was subjected to bizarre sexual gambits involving photos of vaginas and fondling of his genitals. When these methods, death threats, and physical abuse didn’t produce results, the military interrogator told him that his mother would be shipped to Guantánamo and gang raped if he did not talk. He was also subjected to a false kidnapping and threatened with worse torture.
Eventually, Slahi confessed incriminating details to his interrogators, but because of the abusive methods through which they were learned, Couch believed the confession was unreliable and inadmissible. Indeed, he no longer believed he could press charges against Slahi at all.
