Scarfo having an issue with the Gambino's encroaching on philly's south jersey territory was the least of Gotti's problems. The Genovese family wanted all the south jersey rackets after Bruno was killed in 1980. Because of the Gambino's trying to go after south jersey, the Genovese ( bobby manna) wanted gotti killed. Part of it was due to the unsanctioned hit of Castellano, but mostly due to south jersey. Had it not been for an fbi bug in a genovese controlled restaurant that resulted in the arrest of Manna and part of his crew, both john gotti and his brother gene would have been dead. That crew didnt fuck around, they were serious guys.
