For your information Nicolo Rizzuto started to make his moves only after he learned from the CECO commission tape recordings that Paolo Violi and Pietro Sciarra were discussing Nicolo's fate. This was in 1975 and Paolo Violi was imprisoned the same year. Prior to 1975 Nicolo was doing his own thing and wanted nothing to do with Paolo V. This is what sparked meetings with the Bonanno's.
In Vito's case, I do not understand what point your trying to make. I agree that he kept a tight ship and he was good at keeping the peace among all the different clans in Montreal but it wasn't with out incidence. I explained in the same message that he and Paolo Gervasi were feuding and that was well before Vito got arrested.
