Actually, IMO, it is outrage over the MSM and the race baiters and the ineptitude of the NO and LA govts. all blaming Bush.
The local and state govts. had many years to prepare and knew for at least 5 days beforehand that Katrina was on the way and it seems they did nothing.
Again just look at those school buses, that were not used.
It truly is shocking how inept the whole thing has been.
