Hi guys, it's been 4 years since I posted in this forum. Got a question that you all maybe have the answer.

It is widely believe that Vincent Mangano was murdered on order by Albert Anastasia. Prior to Mangano's demise, the twos verbally duke it out on a regular basis, sometimes nearly coming to blows. What I don't understand is, Anastasia was Mangano's underboss - why Mangano did not eliminate Anastasia even though Anastasia did something excessively disrespectful to him? Even Gotti never shows his hatred in front of Castellano himself, he knew the consequences.
