Remember decicco went to feel out the other Capos. Nino was close with Paul. He would've said something and if Paul hadn't killed Roy, Gotti would've been dead. If Roy didn't bring on all the heat that warranted his death, Paul probably would've asked once for those tapes, Neil or no Neil. Gambino would've only asked once. Paul slipped and the rest is history. There was a documentary that explored how Paul killed Demeo because he thought he may rat. But the fbi said they would never except him as a witness because of his heinous crimes. Not even ten years later they use gravano against Gotti.
