2) Should regs and the UCMJ forbid mistreatment of prisoners, then any order to mistreat a prisoner is not a lawful order. It must not be followed, and "I was just following orders" is not even remotely an acceptable defense. The grunts as well as the brass giving the order should be tried and if convicted punished as severely as the law allows.
3) If it's true that Rumsfeld was notified of "problems" with the prisons months ago, and did nothing to investigate, he needs to be dragged before Congress to be grilled, then fired.
4) What Iraqi insurgents did to their prisoners, including the four mercenaries that were killed, mutilated, and dragged through the streets a few weeks ago, justifies nothing. We get to cry out about that on the basis that we stand against that kind of action, that we would never do such things ourselves. If we do it, we lose any credibility to complain about others. If we're not truly the better people, with the better system, we have no business being in that country to begin with. Those of you who disagree need to figure out just what the fuck you stand for.
