Ooooo. Recognized it as soon as I saw the picture.

While this is one of the most serious war criminals in recent American history (and his Brigade commanders who must have known were never charged), I wouldn't say that people should recognize the name off the top of their head. I've met people in the military who've never heard of the My Lai massacre. I'm a history buff, and I looked into the Vietnam War for a long time.

The Warrant Officer, and helicopter pilot, Hugh Thompson, (and his surviving crew) whom stopped the killing gives lectures on ethics & leadership at most of the Officer Schools to this day as an honored guest.
