If you've got complaints about George W. Bush, then fine. But don't sit there and pretend that Rudy Giuliani -- whose primary success in politics was his success in serving as the head of a police state that most Americans would find intolerable -- has anything to offer at this point.
In fact, I'll go one step further and suggest that Rudy Giuliani would be utterly incapable of dealing with the chaos and disorder in New Orleans right now. As a life-long resident of the New York metropolitan area and in his former roles as Federal prosecutor and mayor of New York, he's never had to deal with a situation in which more than 0.01% of the people in his jurisdiction were legally armed.
I agree with your points. I was kind of thinking of kicking out the petulant mayor of NO and putting Rudy in her place. At least, he'd know to deploy police vans on the streets with loudspeakers to provide leadership on the spot. No one's telling anyone what to do, it's very obvious.
The people in charge there now have no clue, and true leadership would provide the overwhelmed police and Guardspeople with a serious force modifier.
