Katrina: The White House knew levees would break
The charge is devastating: That, on August 29, 2005, the White House withheld from the state police the information that New Orleans was about to flood. From almost any other source, I would not have believed it. But this was not just any source. The whistle-blower is Dr. Ivor van Heerden, deputy director of the Louisiana State University Hurricane Center, the chief technician advising the state on saving lives during Katrina.
