Scoble is in New Orleans, and I can tell you that I'm not surprised by his first report from there:

Regarding the neighborhoods here, it’s dark, so I can’t see the full extent of the devastation, but the little bit I can see is simply horrific. Driving along I saw boarded up homes and buildings. Many of which still have spray-paint messages left by rescuers that say whether or not there were any bodies inside.

I predicted as much back on September 3rd, 2005.
