Granted, though the administration handled it badly, the problem goes back to many administrations failing to fund the Army Corps to do the job right the first time.
No, the problem was, those idiots Mayor Nagin and Gov Blanco chose not to follow their Emergency Management Office's disaster protocols. They did no evaluations of the disaster areas and had no idea what they needed by way of assistance from FEMA.
In other words, they got on tv and whined because other people wouldn't come in and do their jobs for them.
