I used to work with a guy that believed that. He said "Why you don't see no white people on tv on roofs." I said "Because they all left before the storm." So apparently George W. Bush hates black people so much he used his weather machine to send a cat 5 hurricane right at NO, then sent in buses to save all the white people, then blew up the levees to flood the black neighborhoods. That was his belief. I told him that they must have been intelligent bombs. They could send the water around the white people's houses and just flood the blacks.
Some people will believe anything Jesse Jackson or Al Sharpton says. No matter how off the wall it really is.
They completely ignore the fact that they were told to evacuate. Now its the government's fault because they decided to stick around and were stranded.
