I thought the American costa nostra does not kill innocent people, family members and people in law enforcement?
I have never been to the USA, but from what I read it does indeed seem the American mafia is more careful in such matters than the Italian one. Still, there were some cases like “Gaspipe” Casso ordering hits on relatives of suspected informants, Carmine Persico ordering a hit on the prosecutor Aronwald and mistakenly killing his father or Salvatore Avellino ordering a hit on the businessman Kubecka who opposed himself to the mafia and provided evidence for the trials.
Yes. And there was a shootout in the Ridgewood section of Queens where a police officer where shot to detah. Genovese member Fritzy Giovanelli was tried for that but freed. But you are correct. The American Mafia is generally much different when it comes to these kind of things than the Sicilian Mafia.
