Department of Homeland Security warned of levee breach

Documents released Monday show that the Department of Homeland Security was warned on August 28 that the storm's surge could breach levees and leave New Orleans flooded for weeks or months. The information came from the department's National Infrastructure Simulation and Analysis Center. The warning was issued in the event that Katrina would be a Category 4 or 5 storm. It turned out to be a Category 5 storm, but was a Category 3 by the time it hit New Orleans. All the same, Chertoff and Brown--not to mention the birthday cake-eating guitarist--were warned.
