Here is a link to an impassioned but objective piece by BBC correspondent Matt Wells - New Orleans crisis shames Americans

The party in power in Washington is always happy to convey the impression of 50 states moving forward together in social and economic harmony towards a bigger and better America.

That is what presidential campaigning is all about.

But what the devastating consequences of Katrina have shown - along with the response to it - is that for too long now, the fabric of this complex and overstretched country, especially in states like Louisiana and Mississippi, has been neglected and ignored.
