Great find on that article, I read a little on how the Calabrian clans work the docks there. I was surprised to find out there was no like central control mechanism like a union. It's just the dock is so vast and under policed that they just " Rob" the contraband before anyone can be any wiser. It's kinda "Democratized" any clan can create contacts at the docks from what I could gather.
It gives more insight to the NY operations, with Calabrian families setting up routes outside the Siderno groups operations. Sending it to their own contacts at the docks on the other end.
