What is the Difference between Michael Brown and Janet Napolitano?

There are two that come to mind which are obvious - first, neither seems qualified to their job. Brown was head of the Arabian Horse Association and Napolitano served as a counsel to Anita Hill. Second, both were in positions of critical responsibility for their fellow citizens. Napolitano seems to have the same kind of denial that Brown did. She first commented on how well her department functioned (the system worked) and then a day or so later - when the obvious flaws in their performance were pointed out - she changed her tune.

Oh there is one more difference. Brown eventually was forced out. It is not clear whether Napolitano will be granted the same treatment.
