Bush fucking knew. Video tape of him being briefed of exactly what happened. Later he made this quote.:
“I don’t think anybody anticipated the breach of the levees. They did appreciate a serious storm but these levees got breached and as a result much of New Orleans is flooded and now we’re having to deal with it and will.”
Will this change a damn thing? Probably not. The Republicans will spin it, the Democrats will say “look, we’re better than that!” and everyone else will ignore it. Which will ignore the real problem. Our government let people die when it knew they had a damn fine chance of doing so. They let people drown, live in a hell hole and crime run rampant.
Welcome to America!
