Bobert, PUHLEEZE don't bother to retype "your arguement"! It was factless to begin with and is the reason we are ignoring you.

While I still place much of the blame on the Mayor/NO and the Governor, the real truth is both of them begged the citizens to leave and were ignored. The Governors aide requesting 500 buses AFTER Katrina (on Tuesday) was perhaps a bit of an afterthought.
Soooo, much of the blame for the fatalities lies with the citizenery.
To answer the question; "Katrina, who was to blame?"

I go with Mother Nature myself.
