The smoking gun

Congrats to Margaret Ebrahim and John Solomon of the Associated Press for breaking what could become a critical story in the Katrina saga:

WASHINGTON - In dramatic and sometimes agonizing terms, federal disaster officials warned President Bush and his homeland security chief before Hurricane Katrina struck that the storm could breach levees, put lives at risk in New Orleans' Superdome and overwhelm rescuers, according to confidential video footage.

Bush didn't ask a single question during the final briefing before Katrina struck on Aug. 29, but he assured soon-to-be-battered state officials: "We are fully prepared."

The footage - along with seven days of transcripts of briefings obtained by The Associated Press - show in excruciating detail that while federal officials anticipated the tragedy that unfolded in New Orleans and elsewhere along the Gulf Coast, they were fatally slow to realize they had not mustered enough resources to deal with the unprecedented disaster.

And then he went off to vacation. Crooks and Liars has the video. And remember -- Katrina is possibly Bush's biggest vulnerability.
