The problem with comparing the murder of Mr. Berg, with the porn in Abu Ghraib prison is that the two are so different. One is committed by low life savages, who are belong to barbaric culture, and violent religion. Every body knows that, and no one is surprised that they are sub-humans. Historically, Moslems have slaughtered so many people; to the extent that the word ASSASIN in the dictionary explains its Arabic Moslem roots. The others, the trail trash Americans in Abu Ghraib, they are belong to the most civilized country the best military, the best religion (Christianity requires us to love our enemies), the best instruction (to win the heats and minds of the Iraqis), and hence the world sense of disbelief/disappointment.

Zell Miller has it simply right.
