As far as Katrina, your right, that was a fiasco. I got a call to drive to New Orleans, followed by a call to not go. It went back and forth a few times. Some rescuers said "screw this" and just went anyway. When they arrived they were assigned to a new "faith based" rescue unit that had never been deployed, had 0 equipment, and no training whatsoever. When a shipment of food and water arrived for the victims the faith squad drank and ate it. They had not even brought their own food and basically needed to be rescued themselves.
This what happens when GWBush appoints the president of the Arabian horse association to be in charge of FEMA. So if your concern is these people taking over the world, fear not. Their utter incompetence is protection enough.
Wow! That made me laugh...thanks
