I think you're confusing Guantanamo Bay and Abu Ghraib. It's the latter where sadistic guards took photos.

Ugh. The pictures in that article are horrendous. The "patriots" will say (and in fact do say -- see the linked article about Lyndie England) that the real crime is not the acts committed but making them public. The same is true of course in China with Tiananmen Square or in Russia with the current military operation.
It's funny how self-declared patriots seem to specialize in making the rest of the world hate and revile their country.
