The sniper studied ninjitsu with one of my teachers. Granted, this was a tough sensi, but I remember him telling me that one of his students, John whatever his name was then, flipped out on the blackbelt test, which involved the student being tossed out in the woods and messed with for several days. (Not me, as a girl I was treated a bit more gently.) Anyway, this guy was hallucinating, the whole nine yards. Not that insanity is an excuse for such heinous behavior. But I do believe that he is insane.
(I read a copy of the Quran that was supposed to be a direct translation from the ancient Persian. The old language was on the facing page (not that I could read it.) I think, that like some translations of the classics, this gave the scholar an opportunity to dispute the translation. It was a lovely translation, anyway.)
