What specific detective work was he referring to?
He was talking about the new york times op ed that called levee money a boondogle in April of this year and then blamed bush for not having sufficient levee hence breach. Credited Freepers and Power Line. Said Freepers doing "good work".
He mentioned the photo of all the buses underwater that has been all over this site for the past few days.
Now everyone who posted that photo, pat yourselves on the back!
