In places like Cleveland , Chicago , Harlem , Kansas city , etc etc how did the italians take over the numbers rackets from the Afro Americans so easily back in the 20's,30's,40's and 50's? I was watching an interview with Quincy Jones about his childhood. He had said that his father built houses for black gangsters in the 30's and 40's until the italians took over the numbers racket's and ran them out of the city. Quincy Jones grew up in Chicago btw
