So president knew what could happen with levees at least 4 days ahead of hurricane Katrina? Yeah no doubt, but every single citizen of New Orleans probably knew as well. From my little research I can say that most people knew ahead of time, even for decades that the levees were vulnerable. New Orleans is below sea level!

"There were many warnings in the late 20th century that a major hurricane or a Mississippi flood could create a lake in the central city as much as 9 m (30 ft) deep, which could take months to pump dry. This warning was augmented by vestigial fears from Hurricane Betsy, and the lasting stories of the Army Corps of Engineers blasting the flooding levees, drowning the poorer neighborhoods of the lower ninth Ward. The Holy Cross Neighborhood Association, (HCNA) representing a substantial group of the aforementioned lower ninth ward, created a lobby against the Army Corps of Engineers furthering work on the levees which might endanger the neighborhoods."

"Mr Brown told colleagues he was worried about whether evacuees sent to the Superdome would be safe and have adequate medical care - but it took four days for a large-scale evacuation of the stadium to begin. In the meantime, images of thousands of people stranded there without enough food, water or medical supplies shocked the world."

Hurricane Ivan in 2004 should've been a wake up call also. So who to blame? Major? Bush? FEMA? Or just plain human ignorance?

But back to the president, he lied once again. Well that's not a big news, we even have a nice video footage. Some long shifts at his propaganda (ehm PR) office these days, I suppose.
