Remember that the officials in Houston had a plan and implemented it for the handicapped, sick and disabled well before hand. They were air-evac-ed outta there, as they should've been. It's just another blot on Nagin's and Blank-O's incompetence to handle a disaster .. and in a place that's always been vulnerable to hurricanes.
The nails of Blancos coffin are firmly nailed in and sufficient in my mind.
