No one could have anticipated the breach of the levees?

In the Brookings Institution's timeline of Hurricane Katrina, considerable doubt is placed on Bush's claim that "No one could have anticipated the breach of the levees". Really, Mr. Bush? The timeline shows that early on August 28th, Department of Homeland Security chief Michael Chertoff and the head of FEMA, Micheal Brown were electronically breifed on that exact possibility. This, in addition to the widespread evidence that a breach of the levees had been feared as a realistic possibility in a Category 3 or higher hurricane if it were to hit close to New Orleans, demonstrates that Bush is either a liar or an incompetent president. If he is not informed of possibilities that other senior members of his administration are told of with the significance of this one, there is a problem. There, of course, is the other possibility that Bush is just a liar, which he has demonstrated repeatedly. Is he really fit to continue to lead a country involved in two wars and a catastrophic natural and man-made disaster at home or should the House of Representative blow the dust off of it's impeachment procedure manuals that have layed dormant since the impeachment of President Clinton for lying about a blowjob?
