I didn't see the show, but I'm guessing the crazy cracker is Charlie LeDuff, who wrote a great book about Detroit that Eupher and I have both read. Detroit: An American Autopsy.
Charlie is on FOX 2, here. He's pretty well-liked by both conservatives and liberals around here, because he tells it like it is. He's the guy who set up Monica Conyers to get verbally smacked down by an 8th grader on television.
He has really taken up the cause of the Detroit Fire Department, which is so underfunded and so overworked.
