Prisoners Of Katrina

The criticism of the government response to Hurricane Katrina consisted primarily of condemnations of mismanagement and lack of preparation in the relief effort in response to Hurricane Katrina and its aftermath. Specifically, there was a delayed response to the flooding of New Orleans, Louisiana. (See Hurricane preparedness for New Orleans for criticism of the failure of Federal flood protection.)
