Not seen in fifty years

Barry Ellsworth has an AllVoices column about Jack Ruby:

Before the fiftieth anniversary of President John F. Kennedy’s assassination, the Dallas district attorney has released twelve boxes of new information on Jack Ruby, the man who shot Lee Harvey Oswald to death.
Never before seen by the public, CBS This Morning was allowed to view the boxes, containing items such as brass knuckles that Ruby carried, his gun holster, and even pictures of a stripper who performed at his nightclub, The Carousel Club, on Commerce Street in Dallas.
There is also a lie detector document of Ruby being asked the question: “Did you shoot Oswald to save Mrs. Kennedy from the ordeal of a trial?”
Ruby answered: “Yes.”
However, a Nodisinfo.com article dated 21 March 2013, disputes that fact. Writer Jeff Morley said he received a call from a woman who was Gail Raven’s daughter. Raven was a stripper who was close to Ruby. The daughter said her mother was still alive and said Ruby “had no choice” but to shoot Oswald.
When Morley asked what she meant, the daughter said her mother told her: “Jack had bosses, just like everyone else.”
No matter which version of the motive is correct, the boxes contain invaluable historical documents.
For example, for years it was rumored that Dallas Police Officer Roy Vaughn, who was on duty guarding the garage ramp that Ruby came through before shooting Oswald on 24 November 1963, had allowed the nightclub owner to slip in.
Oswald was being transferred from the Dallas jail to a maximum security prison.
But retired insurance investigator Dave Perry, who has studied the JKF assassination for decades, was asked by CBS to peruse the contents of the boxes. He found a note from Henry Wade, then Dallas County district attorney, that stated Ruby told him that “Officer Roy Vaughn did not see Ruby.”
Craig Watson, Dallas County District Attorney, allowed CBS access to the documents that had sat for years in a warehouse. Some will be loaned to the Sixth Floor Museum in Dallas, CBS has reported.
“I would imagine when a historian has the opportunity to go through all these documents, they will find little nuggets of jewels they can use to give an explanation of the times back in 1963,” Watson said.
