what really made the Marcello family so powerful was its alliances with criminal networks in florida- trafficanti and texas -civello ,campisi. Marcello even had a piece of the vegas Tropicana and was in with frank Costello in gambling all through Louisiana. with guys like lansky and even the cowboy benny binion -they all had their wars and figured to do business together instead of kill over turf. that's why they had a commission and Marcello was on it.
