Apparently George knew everyone in New Orleans might die, but did nothing. This leaves several possiblities, ranging from the forgiving to the seriously mental.
1) He figured they probably wouldn't be able to build up the levees to sensible levels, so suggested to the town Mayor to evacuate if the weather turned bad. The Mayor encouraged evacuation, but lots of people stayed and died.
2) He said 'Great, they're only poor people and poor people don't vote for me. I think I'll wait for the diaster, then head down, kiss some babies, shake some hands and get boosted ratings, both from the lower porportion of poor people in the area, and the general media love.'
3) He had rather a lot on that morning and weather phenomena were bottom of the list, after management of the war we're officially not still fighting in Iraq, peace process in the Middle East, removing opportunities for anti-Semetic nuclear weapons acquisition in Iran, managing an energy crisis at home (probably), economic difficulties (maybe), bloody-minded activists and smiling for the camera and getting the words in the right order.
Anyway. Doubtless the news in this country will tell us how evil George is, and the news in the US will say how well-prepared he was and how it could have been so much worse. It's not news really - 'Busy politician ignores one of a hundred life-or-death warnings he receives every day'. I only wrote it cause the site was quiet.
