Newsweek issues a correction.

The original version of this story incorrectly reported that Louisiana Gov. Kathleen Babineaux Blanco had been "hesitant to declare martial law or a state of emergency." In fact, Gov. Blanco declared a state of emergency Friday, Aug. 26, before Katrina hit the state.

Who were they listening to? The declaration was a matter of public record, and appeared on the internet almost immediately.
