I don't see why mob buffs aren't more interested in other brands of organized crime. Read about the Albanian, Russian, Armenian, and Greek mobs and you don't find not a single rat. They get busted, everyone keeps their mouth shut. With the Italian groups, on the other hand, there's at least 2-5 rats with every bust. With the American Mafia, guys are flipping over gambling charges, so how can they be trusted to stay quiet when murders are involved?
