Must we look at this as if we've read the Warren Report and nothing else? Ruby/Rubenstein clearly was either a U.S. intel operative or at least had some powerful CIA protection. To say he was just a strip club operator with mob contacts misses the whole point. Do you really trust what we've been officially told about Ruby?
As Castro and his growing number of rebels were attacking Batista's troops, Ruby was commuting between Dallas and the Houston waterfront community of Kemah, TX. James E. Beaird, a poker playing friend of Ruby's, told both The Dallas Morning News and the FBI that Ruby used to store guns and ammunition in a two-story house between the waterfront and railroad tracks in Kemah, TX., in Galveston Bay. On the weekends Beaird personally saw Ruby and his associates load "many boxes of new guns, including automatic rifles and handguns" onto a 50-foot long military-surplus boat. It was Robert McKeown who often piloted the boat to a drop-off point in Mexico, where Castro himself would land his yacht, the Granma, and pick up the arms. As McKeown delivered more and more arms to Castro, these two men developed a close, personal relationship. Their relationship became so close that shortly after Castro took over in Cuba he flew to Houston, TX and met with McKeown in an attempt to persuade his good friend to return to Cuba. Castro promised McKeown that he would be given a high government position or a business concession. When later questioned about Ruby's gun-running activities in Galveston Bay, Beaird said "many people knew all about this because he (Ruby) was so open with it." But unlike Prio, McKeown, and dozens of other people who supplied arms to Castro, Jack Ruby was never charged, indicted nor even questioned by US government authorities. Ruby appeared to have no fear of being arrested for his gun-running activities from 1952 through 1963. Not only did US government agencies overlook Ruby's illegal gun-running activities, but so did the Warren Commission, HSCA, the Church Committee, and the ARRB.
