Harry Shearer points to two recent NPR reports about New Orleans, both of which were "light" and neither of which mentioned the possibility of the Army Corps of Engineers' design flaws leading to the flooding:
...[the two shows were:] the debate on whether to hold Mardi Gras, and the recording of Elvis Costellos' collaboration with Allen Toussaint at Piety St. Studio in the Bywater. Anthony Brookes, in the first story, referred to the cause of the devastation as "the wrath of Katrina"... [the second was more light weight]
In comments, someone says:
The most recent edition of "On the Media" had a good story on the myths of Katrina, along with a bit of gratuitious navel gazing on journalists becoming part of the story.
