"With thousands feared drowned in what could be Americaâ??s deadliest natural disaster in a century, New Orleansâ?? leaders all but surrendered the streets to floodwaters and began turning out the lights on the ruined city â?? perhaps for months."
"If the mayorâ??s death-toll estimate holds true, it would make Katrina the worst natural disaster in the United States since at least the 1906 San Francisco earthquake and fire, which have blamed for anywhere from about 500 to 6,000 deaths. Katrina would also be the nationâ??s deadliest hurricane since 1900, when a storm in Galveston, Texas, killed between 6,000 and 12,000 people."

However, I'm not arguing the psycological impact of a terroist attack. We all know that it's far worse than what this hurricane has done.
