The "most dangerous" neighborhoods in Detroit seem to change from year to year. When I was an undergrad at WSU, the Cass Corridor was widely regarded as the worst neighborhood, with the areas around the Jeffries and Brewster Projects not far behind. About ten years ago, one article I read put the area around 7 Mile and I-75 at the top of the list. There was also a neighborhood off Mack on the East Side where there was a serial killer. Any list of bad anything in Detroit usually includes Brightmoor, but not this time. I guess it depends on where the most drug dealers have decided to set up shop.
