Chin did make his move and in a smart play, he had convoy to Corallo that an explosive should be used to lay blame at the Sicilians were behind it. It worked can the Gotti and the rest of the Gambino family members that were loyal to Gotti did not know who was behind it, and immediately suspected Sicily. We know that Jimmy Brown and Marino in the Gambinos had a hand in it. Gotti beefed up his security after that. Gotti only found out that the Chin was behind the hit after he was paid a visit by the FBI after they caught Bobby Manno of the Genovese family on tape a few years later in his New Jersey hangout talking about how to get Gotti. After that Gambinos, Genoveses, and Lucchese administration members had that meeting in the underground garage. On the surface it looked like hostilities had ended, but Vincent was only giving lip service after Gotti tried to control the Commission vote at that meeting. The Chin was able to kill Johns bodyguard and driver, a powerful soldier who was a good earner for Gotti, and an associate with connections in construction unions. The Lucchese were able to kill a Gotti drug dealer from the Bergin crew, and kill Eddie Lino. John did not know that Vic and Casso were after him until Casso flipped. Lino was the last one killed as Gigante knew Gotti would not be able to walk away from his last arrest. The Chin was surrounded by men he could trust as bodyguards.
