And how?
Brown showed up on television claiming that FEMA was taking care of the people in the Convention Center while thousands of people were shoved in like so much cordwood.
Brown claimed in subsequent interviews that they didn't "bring the right equipment" because the locals didn't tell them what to bring -- and while this points back at Nagin and Blanco, this does not exonerate Brown. His agency should know the basic equipment to bring.
Chertoff's agency is supposed to coordinate what's what in a disaster; his agency should have been in touch with locals in Louisiana, Mississippi and Alabama even before landfall in order to begin to marshal resources. DHS didn't.
Had this been a terrorist-driven disaster, DHS still wouldn't have been able to handle themselves.
As I said, there is plenty of blame to go around.
The locals didn't even look at their own disaster manuals and resources.
Blanco looks like she's been sitting on the couch eating cookie dough ice cream with her deer-in-headlights face. Give her a remote control and that picture would be complete.
