Let's be careful about our use of terms. While it is true that the Chicago family utilized non-italians, it is an Italian organization just like the othr families across the nation. All of the families utilize non-Italians as associates, but only as that.
The Chicago Outfit under Torrio and Capone was an
Italian-dominated outfit. But, as I was careful to point out, the Mafia in Chicago was an altogether separate organization at that time. And while it's true that other families utilized and still use non-Italian associates, advisers, partners, etc., I don't believe any non-Italians achieved the rank, status and operating responsibilities that Guzik and Humphreys did in the Outfit under Torrio and Capone.
