But yeah i agree that Greco's and LoPiccolo's are the people pulling the strings in Palermo, and on top of that Greco is still very young.
Speaking of Trapani , i don't think they have much power there
Within the Corleonesi you had a faction known as the "Palermitani" – led by Bernardo Provenzano and Antonino Giuffrè, Salvatore Lo Piccolo and Matteo Messina Denaro.
