Altobello an olive oil businessman was in league with Luchese the pezzanovante. Presumably both of them supported Joey Zasa
who Vincent killed. While Altobello was supposedly an old Corleone friend, he must have been aggrieved by Michael's refusal to rise up in the commission, just as Luchese was oposed to Michael rising up in Immobiliare. Given all this, when Vincent "betrays" Michael, Altobello introduces him to Luchese as the "hero" who killed Zasa, and they say something to the effect that had they known about Vincent there would have been no need for Zasa, to which Luchese says, "No one wants another Joe." HUH? Am I missing something or is this just more lazy, sloppy writing and continuity?
