Massino's insight about Galante is a real game changer. Makes me think all the guys on the Commission trial weren't responsible for his murder at all. If Galante wasn't the boss, then the Commission didn't need to approve his murder. Some Gambinos were obviously in on it, but it sounds like Rastelli was the main driver.

My guess is that Galante had a lot of clout and Rastelli didn't want to rock the boat by killing him earlier or was too caught up in legal issues. Galante declaring himself the boss would have pushed Rastelli over the edge.
