Just a warning, this is a long response
The book doesn’t mention the NRC finding that the acoustical evidence was void. However the paper by D. B. Thomas refutes the NRC finding as it claims the NRC uses a less reliable (with regards to the timing of) voice transmission to synchronise the timing of the possible ‘gunshot’ sounds with the assassination. It also determines the possibility that the ‘gunshot’ sounds were attributable to random background or electromagnetic noise to be vanishingly small.
To quote the summary of the paper ‘There was a further incongruity in the arguments of the NRC panel, and perhaps irony, in that a broadcast over the police radio sent one minute after the assassination giving orders to search behind the Grassy Knoll for an assassin, was invoked as evidence that there was no assassin on the Grassy Knoll’. Now you can dispute the papers findings but it is a peer reviewed paper and I am just concluding an electrical engineering degree specializing in signal processing and I found it to be a convincing examination.
As to Ruby’s whereabouts before the assassination, the book goes into them in painstaking detail, starting a few months before when there is evidence that Ruby started making a lot of trips around the country to see serious mafia players including Carlos Marcello (New Orleans mafia boss, for reference see Scheim). It also details Ruby’s complete movements from the days preceding the JFK assassination to the Oswald shooting and presents evidence that contradicts Ruby’s version of events for that morning.
I don’t think that it is implausible that, if he was in effect carrying out a mob hit with a premeditated story, that he took deliberate steps to make it look that way. And I don’t think a dog in his car, if you say it was there, blows the whole theory. Now, I understand conspiracies naturally justify themselves but you can drop the condescending tone. Scheim is at pains to show Ruby’s cosiness with the Dallas police of which there are many independent eye witness reports from his strip joint, so if they are to be believed then it is possible that the timing of the shooting was coordinated with the police.
Take Ruby’s own testimony to the Warren commission (click here for original transcript, http://history-matters.com/archive/jfk/wc/wcvols/wh5/contents.htm, I have double checked this and subsequent quotes for their context. I recommend that everyone interested should read it because if we are all conspiracy crackpots then so was Ruby. Most of the tangents that Ruby goes off on Scheim has chased up and found that they implicate Ruby with the mob or give hints to what might have happened),
‘Who else could have timed it [the Oswald shooting] so perfectly by seconds? If it were timed that way, then someone in the police department is guilty of giving the information as to when Lee Harvey Oswald was coming down’. (Ruby, J. 1964, Warren Commission Hearings and Exhibits, vol 5. p 206)
Now this may seem at first to be implying that the notion is ridiculous, but when placed in the context of the rest of his testimony where he constantly (> 4) asked Warren to transport him to Washington because he didn’t feel safe in Dallas and he didn’t trust his attorney (Joe Tonahill, who had represented known mafia men before, see Scheim) and he repeatedly asked for a lie detector test (Scheim proposes that this is because he realises that the mafia isn’t going to pull any strings to get him off).
‘All I want is a lie detector test, and you refuse to give it to me… And they will not give it to me, because I want to tell the truth. And then I want to leave this world…’ (Ruby, J. 1964, Warren Commission Hearings and Exhibits, vol. 5, page 211)
‘maybe I was put here as a front of the underworld and sooner or later they will get something out of me that they want done to their advantage’ (Ruby, J. 1964, Warren Commission Hearings and Exhibits, vol 14 pp 566). This could be a desperate ploy to get himself off the hook but with the amount of evidence suggesting his connections to the mafia I believe that it is very plausible.
Now Ruby would have had to have been absolutely infuriated at JFK’s shooting in order to put himself at risk of life-time imprisonment by shooting Oswald. However this does not gel with witness reports of his manner at the police station the night of JFK’s shooting. Bearing in mind at this time Ruby told police that he was in mourning, television newsman Vic Robertson, Jr. relayed that
‘Ruby appeared to be anything but under stress or strain’, ‘He seem jovial, was joking and laughing’ (Warren Commission Hearings, Robertson Exhibit 2{http://history-matters.com/archive/jfk/wc/wcvols/wh21/contents.htm}) and at radio station KLIF on Saturday morning DF Russ Knight said that Ruby’s face when talking about Oswald didn’t ‘express any bitterness against the man’ ( Moore R. L. (Knight), Warren Commission Hearings and Exhibits, vol 15 pp 257{http://history-matters.com/archive/jfk/wc/wcvols/wh15/html/WC_Vol15_0131a.htm}). In a note to Joe Tonahill (his attorney) that made its way in to Newsweek in 1967 then to the house assignations committee, Ruby wrote
‘Joe, you should know this. Tom Howard told me to say that I shot Oswald so that Caroline and Mrs. Kennedy wouldn’t have to come to Dallas to testify. OK?’ (Newsweek, March 27, 1967, p.21; House Assassinations Committee Report, pp. 158)
In addition Ruby was not patriotic, his gambling partner Harry Hall said to the FBI ‘Ruby was the type who was interested in any way to make money’ (Warren Commissions Exhibit (CE) 1753{http://history-matters.com/archive/jfk/wc/wcvols/wh23/contents.htm}), he ‘could not conceive of Ruby doing anything out of patriotism’ (ibid) and he ‘scoffed at the idea of a patriotic motive being involved by Ruby in the slaying of Oswald’ (CE 1245{http://history-matters.com/archive/jfk/wc/wcvols/wh22/contents.htm}). This is backed up by a friend of Ruby’s Paul Roland who was paraphrased by FBI interviews as affirming
‘from his acquaintance with Ruby he doubted that [Ruby] would have become emotionally upset and killed Oswald on the spur of the moment. He felt that Ruby would have done it for money’ (CE 1184 {http://history-matters.com/archive/jfk/wc/wcvols/wh22/contents.htm})
Finally (I promise) Ruby said in his polygraph hearing in 1964 ‘Oh yes; they didn’t ask me another question if I loved the president so much then why wasn’t I at the parade? Is that an important question to ask?’ (Ruby, J. 1964, Warren Commission Hearings and Exhibits, vol. 14, pp. 564)
I would just like to stress again how impressed I am with this book, Scheim D. E. 1988, ‘The Mafia Killed JFK’, WH Allen & Co. (first published as ‘Contract on America: The Mafia Murder of President John F Kennedy’ and no I am not its publicist in disguise) and the stuff I have mentioned here is just the tip of the iceberg. If you believe the preface, it took 10 years to write (and I believe that due to the extensive research of the HSAC, Warren Commission and police files he would have had to have done) then it is hardly a good way to make a quick buck and more like the dedicated effort of a citizen who is appalled at the state of play in his own country.
One last thing, that is a nice Voltaire quote Godless Sceptic but what is more absurd? That a strip joint owner risked life in jail just to save Jacky Kennedy from the trauma of giving evidence or that the mafia set up Oswald to take the fall and the job fell to that strip joint owner to silence him. I’ll stop writing now.
