Washington also has a moral burden. It was the Federal Government's responsibility to build levees that worked, and its failure to do so ultimately led to New Orleans' being flooded.

It was the Federal Government's responsibility to build levees that worked,

I don't think you can get away with that assertion. We've all learned about how much money the Feds sent to LA for the levees, and how all of the levee boards used it.
LA couldn't even manage to turn control over the levees to the state, let alone the Feds.

The failure of the levees was LA's problem. And the failure to evacuate NO was a problem shared by the gov. and the mayor.
