Casso's next-door neighbor, Philip Carlo, wrote a book about him that had a lot of Casso's own claims in it. Casso says the government took all of his information and then fed it to Sammy Gravano, but that they were suppressing Casso's information on numerous other murders and drug deals that Sammy had never confessed to (and would obviously destroy his credibility on the stand). And that the Feds wanted Gotti and would do anything they could to get him.

He also says he was offered a five-year deal but the FBI never honored it, and he had nothing in writing.
