Although it's seems clear that Katrina is a government own goal designed to follow up on 9-11, the immense... backwardness of FEMA is amazing, and heads will not roll - because the US is already a dictatorship. W didn't win either election, and no future president needs to either, with black box voting.
Other stories of FEMA incompetence/murderousness is of turning back 500 swamp type boats, only letting one into NO. And rejecting the federal passenger railway service (AMTRAK) their offer of trains for evacuation. The signs are all over this that the Devil is in total control of the US administration.
