How is it a conspiracy? There were serious warnings about a virtually certain disaster ("it's not if, it's when") from the US Army Corps of Engineers and from FEMA (back in 2001), there had been projects in the works for fortifying the levees that hold back Lake Pontchartrain, and in 2004, the Bush administration cut the funding by 80%, presumably becaus ethey didn't think it was that important.
I'm not making this up. FEMA and the US Army Corps of Engineers are hardly some wacko left-wing organizations.
It really doesn't make you angry that some of this could have been prevented??
