Soldier Gets 1 Year In Abuse of Iraqis

At some point, Sivits said, a platoon sergeant called down for Davis to stop. "That's enough," the sergeant yelled out. Davis left the room then. Sivits said Harman later wrote "rapeist" on the leg of one of the detainees.

After the prisoners were stripped, Sivits said, England pointed at and made fun of their genitals.

In another incident, Sivits said he saw Frederick strike a detainee in the chest so hard that someone had to get an inhaler to help the man breathe.

Sivits choked up as he recounted how he told the prisoner to watch his chest and imitate his own calm breathing. Sivits said a medic checked the man and said he was fine.

Later, Sivits said, Graner punched a prisoner in the head and complained his wrist hurt. "I told Corporal Graner, I said, 'I think you might have knocked this guy out.' "

Sivits said he watched as the soldiers put the detainees into a pyramid. He acknowledged photographing Graner kneeling on prisoners with his arm cocked back as if about to strike one.

"It was bad enough," he said in court. "They were embarrassed to be in there, what we were doing to them. They didn't see the picture, but they could hear the click and see the flash through the sandbags" that covered their heads.

Sivits said he left when Frederick and Graner forced the prisoners to masturbate. After hearing the account, Yawar and Sumaidy left the courtroom.

"When that started, I had enough and left," Sivits said.

As he was leaving the area, Sivits said, Frederick called out to him: "You didn't see" anything.
