You explicitly stated that the Detroit Family is entirely legitimate, which is dead wrong. While a great deal of the sons and grandsons of deceased ranking members are legitimate businessmen, there are still plenty of them who chose to go into the "other business" -- booking, shylocking, and extortion.

You referred to Vince Giacalone above. If it's the same Vince who is in his 50's and married to Rita, then he is absolutely a made member of the Family, and is directly involved in sportsbook operations. He is Jackie's (soon-to-be boss) younger brother.
