The clash between the Grecos and the La Barberas involved an old and a new Mafia. According to Antimafia judge Cesare Terranova the Grecos "represented the traditional Mafia, the Mafia in trappings of respectability … and they are linked by a dense network of friendships, interests, and protections with the leading Mafiosi of the Palermo area. They occupy a position of preeminence in the sector of cigarette and drug smugglers. The La Barberas, in contrast, come out of obscurity and their power consists especially in their enterprising ways and their following – a determined band of professional killers."
