Kind of like how the old Elmwood Park Crew of the Outfit imploded after guys like Johnny DiFronzo and Joe Andriacchi got tired of the street rackets after making millions of their own in real estate and construction. The Arm, your knowledge of Buffalo and Chicago vis a via Rockford is somewhat of a clue as to your identity perhaps?? Or perhaps as to whom you may have known??? There is a well-known link between The Outfit and The Arm as I'm sure you are aware
