Gotti was not the reason the mafia fell. He was not the only one that took part in the Castellano overthrow either, he had many captains in on it, including Gravano. If a radio host who covers the mafia chooses to praise Gotti as a mobster that does not mean he is unfit to discuss the mafia. A few people are too worked into an uproar over Gotti, and it is evident in the way they are so desperate for his movie to fail.
