You don't need proof to correct this simple discussion. Luciano killed Maranzano because he held the postition of Capo di tutti Capi, and changed he mafia by changing the structure of the american mafia to have a commission. Ok, maybe Carlo Gambino was in his time the most influencial and powerful boss in America but he still was not the Boss os Bosses, simply because that position has not existed since 1931.
