So, why don’t they show these pictures to the world?
Decency? I don't know that of course, I'm not saying that I'm sure about this, but not releasing photos of people that are too undignified or drastic is a relatively common policy.
Do you by any chance happen to have believed the US lies about weapons of mass destruction in Iraq, which the US lied about to invade Iraq, and killed hundreds of thousands of innocent civilians?
I'm not from the US and I was not yet following US/international politics at that time. Also none of the people I talked about were americans ("our" ambassador being czech, a journalist-editor from France also confirmed seeing the photos), so I don't see it as particularly relevant anyway.
By how much is it worse than burned babies, which were released?
Plus, notice that I said it's plausible, not that I believe one version or the other. And, again, even if we say that it was a lie and therefora a fuck up and journos did not sufficiently crosscheck the validity and several people who claim to have seen the photos are lying even if it could cost their careers, in the light of the colossal fuckup with the hospital parking lot bombing that endangered diplomatic ties with several countries and started protests in the streets of several countries, this was relatively minor and pretty well handled.
