I think that's certainly true, IF they know who these guys are.

If they are fresh off the boat so to speak, and keep it low-key, like ghost hitters/shooters, people may or may not know who they are.

I would be interested if the American wise guys know all the Calabrese gangsters operating in NY?

You think they are all on record with the Gambinos? Or some with the Genovese? Other families even? All that heroin in Jersey? Is that the Gambino Zips?

If they were operating in their territory, I would venture to guess that the NY families keep tabs on em, just so they don't step on each other's toes.

The thing is though, outside of narcotics, these groups might not intersect much. And the Old world gangsters just have a different mentality, maybe this edict was restricted to Gambino members and not all of NY?

Few questions to ponder....
