"The enlisted men were just the ones carrying out the orders passed down to them!"
If you are correct, then why hasn't one of the accused abusers, or the confessed abuser, named an officer or senior NCO who gave them orders to engage in the conduct for which they face punishment? All one of the accused has to do is name an officer who gave the orders and claim the officer told him/her that the detainees weren't under the protections of the Geneva Conventions, since they were not wearing uniforms when captured, and the enlisted person could make the argument that he/she was following a legal order. Why would the enlisted persons take the blame for such an officer or officers?
"Why would the enlisted persons take the blame for such an officer or officers?"
They wouldn't, and it would be unethical for their counsel at court martial to let them . . . Everyone culpable needs to fact their day in court.
