Detroit schools haven't ordered new textbooks in 19 years. Students have reported having to bring their own toilet paper. Teachers have reported bringing hammers to class for protection. Declining enrollment has forced 67 school closures since 2005 (more than a quarter of the city's schools). The graduation rate is 24.9 percent, the lowest of any large school district in the country....We all know it's bad in Detroit, but I had no idea just how bad.
