to trace the holder of the post office box shown on the "Impeach Earl Warren" sign and to locate Weissman's name in a Dallas city directory 1242 also tends to indicate that in fact he was not familiar with Weissman. Had he been involved in some type of unlawful activity with Weissman, it is highly unlikely that Ruby would have called attention to Weissman as he did.

Investigation has disclosed no evidence that Officer J. D. Tippit was acquainted with either Ruby or Oswald. Neither Tippit's wife nor his close friends knew of such an acquaintanceship.1243 Tippit was not known to frequent nightclubs 1244 and he had no reason during the course of his police duties to enter Ruby's clubs.1245 Although at the time of the assassination Tippit was working weekends in a Dallas restaurant owned by a member of the John Birch Society, the restaurant owner stated that he never discussed politics with Tippit.1246 Persons close to Tippit related that Tippit rarely discussed political matters with any person and that he was a member of no political organization.1247 Telephone records for the period following September 26, 1963, revealed no suspicious long-distance calls from the Tippit household.1248

Tippit's encounter with Oswald following the shooting of the President is indicative of no prior association between the two men. Police radio logs show that, as part of general directions issued to all officers immediately after the assassination, Tippit was specifically directed to patrol the Oak Cliff area where he came upon Oswald.1249 His movement from the area which he had been patrolling into the central Oak Cliff area was also in conformity with the normal procedure of the Dallas Police Department for patrol cars to cover nearby districts when the patrol cars in that district became otherwise engaged, as occurred after the assassination.1250 Oswald fit the general description, which, 15 minutes after the assassination, was broadcast to all police cars of a suspect described by a bystander who had seen Oswald in the sixth-floor window of the Texas School Book Depository.1251 There is thus no basis for any inference that, in approaching Oswald, Tippit was acting other than in the line of police duty.

Allegations of Cuban activity.--No substantiation has been found for rumors linking Ruby with pro- or anti- Castro Cuban activities, 1252 except for one incident in January 1959 when Ruby made preliminary inquiries, as a middleman, concerning the possible sale to Cuba of some surplus jeeps located in Shreveport, La., and asked about the possible release of prisoners from a Cuban prison. No evidence has been developed that the project ever became more than a "possibility". Ruby explained that in early 1959 United States sentiment toward Cuba was still favorable and that he was merely pursuing a money-making opportunity.1253

During the period of the "jeep sale", R. D. Matthews, a gambler and a "passing acquaintance" of Ruby, returned to Dallas from Havana where he had been living. In mid-1959, he returned to Cuba until mid-1960.1254 On October 3, 1963, a telephone call was made from the Carousel Club to Matthews' former wife in Shreveport.1255 No
