Gee,
how have thousands of Americans "detained" in prisoner of war camps managed to survive sane. What are they doing at Gitmo that was not done in spades in the Philippines or Germany.
Maybe "Bisher's treatment" can be trademarked.
What a propaganda article from the Observer!
Sadly, not all did.
OTOH, a few (Brits, anyway, I'm not sure about Americans) successfully feigned mental illness to win release from the Germans on medical grounds. This last was my first thought when I read this.
