Digby speaks to what I've been so angry about: that people weren't allowed in to help, and the people in New Orleans weren't allowed to just walk out.:

I think we can all understand the overwhelming nature of this disaster. And there should have been more adequate planning and a better response, no doubt about it. But the decision to deny immediate aid to people in the city is the worst decision of all. Read that story. These tourists were treated like shit by the authorities everywhere they went, just like the locals. Whoever made the decision to deny those people relief and then deny them the ability to leave when they tried to save themselves has blood on his or her hands.

Indeed.
