Direct quote from the KSBW article Sawzaw linked to in another thread:

"This is a local levee. They knew it's prone to flooding. That's why it was under a mandatory evacuation order. About 20 people or so didn't leave," said Col. Mike Edmonson, superintendent of Louisiana State Police.

The guy said "local levee". That means a levee maintained by local government, not the Corps of Engineers, not President Obama personally, not even the state of Louisiana, but the parish or town itself.

It's probably a good idea to actually read the entirety of an article before citing it as something that substantiates your viewpoint. Otherwise, it might do nothing but help you insert your foot further into your mouth.
