Because it wasn't "outrageous" that an evil dictator such as Saddam would do such things.
Of course the Muslim community was appalled at the things that Saddam did. But they expected that. When you expect something, it's not a big deal. No one was expecting this of the US military. It's almost a betrayal to them -- to display yourself as one thing and to do another. Betrayal and dishonesty does not go very far in the Muslim world.
Prior to 9/11, weren't you appaled when you heard the things that were occuring under Saddam's rule? I'm sure you were. But were you outraged? Probably not. You likely that it was a horrible thing, that the man needed to be ousted, and all sorts of other things, but it wasn't the same feeling you probably have now.
He also didn't have the gall to photograph and videotape every single tortuous thing he or his sons did to people. And if he did, it wasn't widely distributed.
Would the world be as upset if they heard the US was abusing prisoners? No. We heard that in Mid-January. But pictures. Pictures speak volumes. Pictures make things personal.
