You don't have to waste your time, no books you need to read either. Just read two autopsy reports; one Sciacia, shot in the head, severed Montreal from New York. Second, Sal Montagna, shot, and clarified exactly the position the Bonnano "Boss" held in the scheme of Canadian oc.
This is no disparagement to the NY mob, but an acknowledgement of the reality. You got the Rizzutos, seven Calabrian families, powerful Hells Angels and street gangs, it's another " New York" up there.....
