If Gotti had all those guys contacted, except the Genovese, why'd he continue to cover his ass? Wouldn't he then have the majority of the Commission vote, with the Lucchese's and Colombo's siding with him against the Chin? Bonanno's had no say anyway, so Massino's thought didn't matter. We know the Lucchese's sided with Gigante when he wanted Gotti hit, and even participated. The Colombos had they're own problems, but I just dont see why Amuso and Casso would be for the Castellano hit, only to pussy out when it got deep and someone had to pay. They knew who the real boss was, why not tell Chin to screw himself and hit him on one of his public walks later on down the line.
