we'll have to disagree on that one. if someone hurt my kid, I wouldn't be thinking to stack that person in a homoerotic pyramid and photograph him for revenge. that just wouldn't "click" for me as a form of retribution. These prisoners didn't hurt your kid, nor did they hurt the kids of any of the guards.
But the guards despised them all the same, and wanted to humiliate them.
there has to be something else "wrong" with these guards - homoerotic pyramid construction followed by photographs is not what a "normal" person would do in my opinion.
