A few other facts we should keep in mind about Jack Ruby and his shooting of Oswald:
* Dallas police sergeant Patrick Dean, who was close to the city's Mob boss, Joe Civello, failed a lie detector test with regard to his reassignment of police guards away from the elevators and a door to a stairway next to the stairs just before Ruby shot Oswald.
* Former Dallas police officer Billy Grammer reported that on the night before Ruby killed Oswald, he received a call from Ruby at police headquarters warning that Oswald would be shot the following evening. Grammer said the caller did not identify himself, but that he was sure the voice was Jack Ruby's. Grammer said he was well acquainted with Ruby. Grammer further reported that Ruby seemed to be aware of all the plans to transfer Oswald on Sunday from police headquarters to the Dallas County Jail, that he knew about the decoy vehicle assignment, and was aware of the approximate time the transfer would occur.
* Two WC staffers wrote the following in an internal Commission memo:
In short, we believe that the possibility exists, based on evidence already available, that Ruby was involved in illegal dealings with Cuban elements who might have had contact with Oswald.
* According to an 11/25/63 Associated Press report, William Crowe, an entertainer who had performed at Ruby's Carousel Club, told an AP reporter he was "positive" he had seen Oswald in the club.
Dallas Morning News reporter Kent Biffle said Crowe told him the same thing several days later.
* Karen Carlin, who had been a dancer at Ruby's club, told FBI agent Roger Warner on 11/24/63 that "she was under impression that Lee Oswald, Jack Ruby, and other individuals unknown to her, were involved in a plot to assassinate President Kennedy."
* Another Ruby dancer, Janet Conforto, told Dallas newsmen shortly after the assassination that she had seen Oswald in Ruby's club. Yet another Ruby dancer, Kathy Kay, told the
Dallas Times Herald the same thing in 1975.
* Four Dallas deputy constables told the
Dallas Morning News in 1976 that shortly after the assassination they examined a box of handwritten notes and other papers in the Dallas County Courthouse that linked Ruby to Oswald.
* In 1990 the Attorney General of Texas, Jim Mattox, announced that his mother had told him she once saw Ruby and Oswald eating dinner together in the restaurant where she worked.
