It may be difficult to believe in the early 21st Century, but Detroit, Michigan - "The Motor City" - once reigned as one of the most thriving and economically healthy metropolises in the United States, sustained by its role as the nerve center of the auto industry. But calamity soon arrived, first with widespread plant layoffs, then with the horrific race riots of the late 1960s - and as time rolled forward, the city only grew more impoverished and crime-ridden. Downtown businesses, such as the famous Hudson's Department Store, closed shop, and many inner-city Detroit neighborhoods grew as derelict and decrepit as any urban areas in the United States. By the year 2000, Detroit ranked in the top four of the most dangerous American cities to live in, often falling second only to Camden, New Jersey. As directed by Alan Bradley, the documentary Rollin: The Fall of the Auto Industry and the Rise of the Drug Economy in Detroit offers a historical chronicle of Detroit's tragic, meteoric downfall.
