Chicago is right. Dellacroce saved Gotti´s ass from getting killed in 1982. When Dellacroce died, Gotti became fair game. It just happened (perhaps because Castellano´s hands were tied at that moment being indicted and all) that Gotti was quicker to resort to violence. We have seen in the past that in many cases when a boss was killed, the aggressor was quick to claim self defense in front of the Commission. I´ve often wondered why Gotti didn´t do that? He was certainly entitled to it. And the only answer I can think of is that the Commission, which had handled these kind of troubles in the past, was simply non-functional at the time.
