U.S. in violation of Geneva convention?

The U.S. official's way of behaving like Texas rednecks are embarrassing. Not only are they cheering "we got him" like a child who can not withhold his enthusiasm. Displaying Saddam the way they did are also possibly a clear violation of the Geneva convention as far as I can tell. What was that quote by Nietsche again? One person who actually did behave in a respectable manner was the President. No lame "we got him" or cowboy hats there. At least not this time.
