I just know that if you are a really good moneymaker/earner then it doesnt matter if you made your bones or not. with all of costellos political power I think he was very useful even if he never committed a murder. On that note, it has been said that you just had to participate in the murder conspiracy ( planning, cleaning up, crash car, getaway driver, dumping body etc) and not actually had to pull the trigger. If that is the case then I can see it possible that a lot of people made their bones, but to think that everyone has pulled the trigger is foolish and plain wrong and we all know it.

Also, by watching that 60 minutes interview with Bonanno its obvious that he did not like Luciano, I would think that he held a grudge for murdering Maranzano, his idol.
