Today Obama will be making an extremely short stop in New Orleans. Or what my favorite NOLA blogger calls a “tinkle-stop tour.” In New Orleans, he’ll be visiting a charter school and participating in a town hall meeting in the Lower 9th Ward.

In contrast, his next stop will be San Francisco, where he’ll be spending four times as much time–16 hours. This has caused Harry Shearer to say,

Total elapsed time in SF: sixteen hours. They must have experienced a hell of a federal disaster there. Four times worse, you figure?

Often when people including those in government and the mainstream media who should know better refer to the events of 8/29, it is merely as “Katrina” or “Hurricane Katrina”.

There were actually two catastrophes that happened that day: the storm, which passed to the east of New Orleans, devastating with ferocious winds the Alabama, Mississippi and eastern Louisiana Gulf Regions, which was a NATURAL disaster, and the falling apart of New Orleans’ federally-built and maintained levees, which was a MANMADE disaster due to poor engineering.

While the use of Katrina as shorthand to cover the two events is easy (I’ve even done that at times) it’s misleading because of the implication that the flooding of New Orleans was a natural disaster. And this matters–more below the fold.
