Based on his bio, he's served as a commander/commandant of some entity at least 6 times, including at the squadron, group and wing levels. It would be interesting to see how many people have been punished by him for the exact same crime. There has to be a base press release/blotter article with a quote from him talking about how dangerous DUIs are and how one of those is enough to end a career.
In all reality, I'm not surprised at the (lack of) punishment he is receiving--we've seen it time and time again with people who wear stars.
