Kennedy. He "All three of them were very close friends, and, when we look at Jack Ruby's telephone records, we find an astonishing peak in the number of out-of-state calls in the months before the assassination--it's actually 25-fold greater than in the month of the previous January. Most of those calls are to organized crime figures, in particular to top associates of Marcello, Trafficante and Hoffa.
