When Buscetta turned informant, the whole commission went on the run or in jail.
When Valachi did, no indictments at all.
I understand the laws in 2 countries are different, yet I think in this case the USA wasted an excellent opportunity, it would have been funny see Tommy Lucchese doing 100 years. I mean, it's one thing to put there somebody like Riina or Gotti who were in jail like at home, it's another to put there a half-white-collar guy like Castellano, Lucchese etc
