The mob is EVERYWHERE that there's any money.
Up north? Yeah, we had plenty of mob activity in CT, RI too but let's not pretend there's no organized crime in Miami.
Fuck, the Ukranian mob has call centers in North Carolina with their shipping and receiving in Staten Island NY.
To OP, the reason you don't see effective organized crime syndicates making the news much is because they're trying to stay protected and keep the money flowing. If you know who they are, they're fucking up.
To this end, there will always be layers of protection.
A man can drive a truck from point A to point B because your friend has done some runs for them already and you may meet a dude at the pickup, and another at the drop off, but you never meet or even hear the name of the lieutenants that those guys answer to, much less their bosses or the Capo out of Providence.
Also if you really want to hear some crazy stories there's a lot of retired mob guys from various syndicates in Santa Monica, not just Whitey Bulger but a lot of Russian and Ukranian dudes too.
