For the protection required for a physical visit, who can spare the bodies right now? I'm unnerved by the number of "Old Southern Boy" sheriffs and politicians and the like literally reduced to tears right now.
Communications are minimal (governments are probably relying on CNN right now... memo to Fox: we give more of a rip about the human toll than about how far inland the Biloxi casinos migrated), access is extremely limited, and it's kind of hard to render aid to New Orleans when you know you're about to deal with MORE water, not less.
That doesn't mean Bush is off the hook for possible lack of preparedness, or perhaps a relatively heavy rotation of Guard troops in Iraq, or for perhaps being such a party to the process of gutting government that there won't be anywhere near the rapid response there should be... but you generally have to know what to fix in order to bring the right tools.
Pounder, a good point about the process of gutting government and having all the necessary resources in place for rapid response. All this may be a major political discussion for much time to come. This will be coupled with enhanced concern pertaining to the rapid rise in fuel costs.
Of course, just observed one of Murdoch's FOX NEWS ALERTS showing an Air Force One Flyover. That photo-opt alone, probably held up some choppers and related rescue activities.
