Following orders does not mean you do not have to be responsible for your actions. We learned that at the Nuremburg Trials, albeit that this abuse isn't as bad as what the Nuremburg Trials were for.
Especially since the orders were coming from Graner, the ringleader, to the others. If you're implying higher ups "ordered" this nonsense, you are flat out wrong.
??? Who was Following orders? These twits were rogue.
