And another Louisiana politician goes down. Derrick Shepherd, State Senator representing Marrero, is saying the FBI are just mad because he didn't give evidence against Nagin and Karen Carter. Nagin? Sorry dude, but I seriously doubt that the FBI are out to get Nagin. He may be guilty of many things: Incompetence? Sure. Being a "knucklehead"? Sure. But I don't buy that he's corrupt or even being investigated. He seems uncorruptable, like Charlie Brown. And probably just as competent.
