Ruby was a low level manager of a Strip Club
Oh my. This is just comical. His phone records prove he made numerous phone calls to contacts at the highest levels of the Mafia in the weeks leading up to the assassination. Guess who visited Ruby after he was arrested? The Mafia boss for Dallas, Joseph Civello. You might break down and read the HSCA's section on Ruby's Mafia connections. He was much more than a "low-level manager of a strip club." The Mafia boss of a large city does not visit a low-level club manager in jail.
On the day he shot Oswald, he was across the street at a Western Union wiring one of his strippers some money mere minutes before he shot Oswald. He was there at the time Oswald was supposed to be transferred. Oswald was delayed.
He only anticipated being at Western Union a few minutes and had his favorite dog waiting in the car.
He saw a commotion across the street at the Police Station so Ruby wandered over. He arrived moments before Oswald came down and was in position to make the shot.
Sigh. . . . Just sigh. . . . The HSCA destroyed this mythical cover story. The HSCA proved Ruby lied about how he got into the basement and noted that Ruby himself admitted to his second attorney,
in writing, that his story about why he shot Oswald was false--the note surfaced after the Warren Report was published. Ruby called the police department and warned them that Oswald would be shot if they didn't change their transfer arrangements.
There was a Western Union office blocks away from Ruby's residence in Oak Cliff, yet he drove all the way into downtown Dallas to buy the money order. After he parked his car in a garage across the street from the downtown Western Union office, his odd behavior continued: Instead of keeping his keys and billfold in his pockets as anyone would normally do, he put his keys in the trunk of the car, then locked the trunk, with almost $900 in cash inside, and placed the trunk key and his billfold in the glove compartment, without locking the car doors. Are you kidding me? Who does that? That makes no sense.
Carrying almost a grand in cash would have been a good excuse for carrying a handgun. But with the cash strangely placed in his car trunk with the trunk key in the glove box and the car doors unlocked, he had no reason to carry a concealed and unlicensed handgun supposedly just to get a money order.
Furthermore, if Ruby was merely on his way with his dog to his nightclub on a Sunday morning, when the nightclub was closed, why was he "dressed like a detective," with a suit and tie, instead of just wearing casual clothing?
His actions that morning hardly seem unrehearsed and spontaneous, much less credible; rather, they come across as clumsily staged and contrived in an effort to make his shooting of Oswald look like a spur-of-the-moment action.
And then there's Karen Carlin, who supposedly called Ruby that morning and asked him to send her money for rent and food and for whom Ruby bought the Western Union money order. When Secret Service agent Roger C. Warner interviewed Carlin later that day, in Warner's words, she "twisted in her chair, stammered in her speech, and seemed on the point of hysteria." She told Warner, according to his Warren Commission affidavit, that she was "under the impression" that Oswald, Ruby, and others unknown to her were "involved in a plot to assassinate President Kennedy and that she would be killed if she gave any information to the authorities." She later calmed down in the interview and said "she had no information in her possession" that Ruby was involved in a conspiracy, but she asked that all she related "be kept confidential to prevent retaliation against her in case there was a plot afoot." Months later she testified to the Warren Commission that she called Ruby around 10 o'clock that morning to ask for money for rent and groceries. She also testified that she thought Ruby "had connections with Lee Harvey Oswald," but she insisted there was "nothing to base it on, except my own opinion."
Your "history" is decades out-of-date.
We should keep in mind that two documents released in 2017 reveal that Ruby had advance knowledge of the assassination. The documents reveal that shortly before the shooting, Ruby invited a man named Bob Vanderslice to watch JFK’s motorcade with him and to “watch the fireworks.” Ruby met Vanderslice at the Postal Annex Building in Dealey Plaza before JFK’s motorcade entered the plaza. The two men then watched the shooting. Ruby did not know that Vanderslice was an informant for the Intelligence Division of the IRS office in Dallas. When Vanderslice saw news reports in 1977 about a new JFK assassination investigation, he decided he should tell his IRS contact about the incident, which resulted in two reports being filed on the matter.
