You have to give it to the Mafia in Sicily, they have done an outstanding job at keeping murders down to a bare minimum and instead focusing on making money and corruption. Anytime there's mention of murders it's murders that occurred decades ago. That takes a lot of discipline and order.
As soon as Provenzano took over , he focused on totally different tactics, low-key , no war against the state , but work with the state , corruption and making money only. Also people who were on top 40-50 years ago were street people , people on top today are lawyers,bankers and so on.
