Here is his version of the Abu Ghraib story in an interview with Democracy Now!:

And I remember just sort of questioning the guy, saying, “Do you really feel proud of having shot an unarmed man who threw a stone?” He was like, “Well, I’m doing my job.” It was a very machismo thing, to have killed someone. I felt this immense loathing and this immense disgust for the whole incident.

Here is his version in the Herbert column:

Mr. Delgado confronted a sergeant who, he said, had fired on the detainees. “I asked him,” said Mr. Delgado, “if he was proud that he had shot unarmed men behind barbed wire for throwing stones. He didn’t get mad at all. He was, like, ‘Well, I saw them bloody my buddy’s nose, so I knelt down. I said a prayer. I stood up, and I shot them down.’

For what it’s worth…
