The one I remember about Shep was when he was on a bridge and some poor Department of Public Works employee showed up in a pickup truck. Shep pounced on him and browbeat him with questions and accusations that were undoubtedly WAY above the guy's paygrade. Geez, you would have thought that poor guy was a mass murderer. I'll betcha dollars to donuts that ol' Shep didn't take the same attitude with Blanco, Nagin or Brown.
