"The military released three grainy black-and-white photos of what it calls the “segregation boxes” used in Iraq. They show the rudimentary structures of wood and mesh. Some of the boxes are as small as 3 feet by 3 feet by 6 feet tall, according to military officials. They did not release a picture of a box that size.
The military said the boxes are humane and are checked every 15 minutes. It said detainees, who stand in the boxes, are isolated for no more than 12 hours at a time."
