I think it's rather immature and small-minded to judge the power of the Mafia in Italy by whether or not they're still killing judges, politicians, bankers, police, journalists, etc. Just because they're not leaving corpses everywhere doesn't mean that they don't have huge power and influence within the political and business spheres of the upperworld, as is evident by numerous investigations, arrests, and dissolution of several local governments due to Mafia infiltration. A crime syndicate doesn't have to leave decapitated bodies on the streets and bodies hung under highways to be powerful or a force to be reckoned with, the cartels are just loud about it.
