Joe Adonis
During the 1940s and 1950s, when the national syndicate was dominated by the Big Six, Guzik and Accardo flew east weekly to meet with the other heads of the organization: Joe Adonis, Frank Costello, Meyer Lansky and Longy Zwillman. The only serious legal problems that Guzik ever faced were with the IRS, and he eventually spent a few years in prison. At the Kefauver Committee hearings, he pleaded the Fifth Amendment on the grounds that any response to the questions might "discriminate against me."
