So you think the world wide publicity over the abuses at Abu Grahib was a good thing?
If you want to compare this to Abu Ghraib you have to tweak a few things. Had Calley sent in photos of the massacre and claim that they were ordered to do that on a daily basis in order to save his sorry ass from prison then we'd have a proper comparison.
The military was properly handling Abu Ghraib and it went public to save some sorry asses. My Lai went public because the gov't tried to save some sorry asses.
