We've Got It Under Control, Cont'd

Via Cafe Hayek, it appears that the Red Cross and other aid agencies were prevented from entering New Orleans to provide assistance by the National Guard. From the Red Cross website:

The state Homeland Security Department had requested–and continues to request–that the American Red Cross not come back into New Orleans following the hurricane. Our presence would keep people from evacuating and encourage others to come into the city.

Doesn't that imply that the folks in charge thought that sending any kind of relief effort was a bad idea?
