As compared to the New Orleans mayor's plan...
as seen here. I've seen a satellite photo that shows 255 flooded busses in that parking lot. If they could've carried 40 people each, that would've been good for 10,200 people per trip.
It was the state and local officials' responsibility to execute their own evacuation plan. Perhaps you're one of those people who think FEMA is responsibile for everything and the state/local officals aren't responsible for anything.
