My reference to the Bureau of Prisons and the War Crimes Tribunal at The Hague (and I’ll add the West Germans with the Baader-Meinhof Gang) wasn’t to say whether or not it’s ethical. I was pointing out that it’s legal and not unusual. People are only talking about it now because of the anti-Gitmo meme.
As for ethics, letting a detainee starve to death because they’ve been sucked in by peer pressure isn’t ethical either. It’s astonishing that anyone could think it would be.
