Researchers have long recognized that Jack Ruby's stalking and murder of Oswald is clear evidence that JFK was killed by a conspiracy. Researchers have also long recognized that the WC's version of Ruby's motives and actions is not only wrong but downright silly.
The WC dismissed key evidence that proved Ruby's action was not a spontaneous act of grief but a carefully planned execution. Around 3:00 PM on Saturday, 11/23, Ruby returned to the Allright Parking Garage and again telephoned KLIF radio to try to find out when Oswald would be transferred. Garnett Hallmark, who worked at the garage, was standing next to Ruby while Ruby was on the phone. Hallmark heard Ruby's end of the conversation. Hallmark told the WC that after Ruby mentioned that the transfer might be delayed, he said, “I understand they are moving Oswald over to the county jail" and "you know I'll be there.”
So Ruby was not at the DPD building by chance just before Oswald was supposed to be transferred. He was there because he planned to be there.
However, Ruby's plan was to try to make his silencing of Oswald appear to be an unplanned, spontaneous act based on his supposed grief over JFK's death and his alleged concern for Jackie. That's why he sent a Western Union wire transfer to one of his employees minutes before he entered the DPD basement, when he could have just as easily given her the money in person the next day. That's why he left his two dogs in his car (along with thousands of dollars in cash).
But Hallmark's testimony alone destroys this tale. The day before the Oswald transfer, Ruby was on the phone trying to find out when the transfer would occur, and once he thought he knew, he said, "I'll be there."
Hallmark also testified at Ruby's trial, and Hallmark's testimony was crucial in proving that Ruby did not act spontaneously but that he stalked Oswald and planned his silencing of Oswald in advance.
Another big hole in Ruby's story was his claim that he was never at Parkland Hospital on the day of the assassination. Seth Kantor, a respected journalist who knew Ruby well, saw and spoke with Ruby at Parkland soon after the shooting. Incredibly, the WC chose to believe Ruby over Kantor.
Here's a good article by John Armstrong about Ruby:

If anything, the involvement of Jack Ruby is indictive of no conspiracy. There were three golden opportunities for the DPD to kill Oswald before his arrest without the complex and risky necessity of recruiting someone else to do that. At the TSBD, the Tippit scene, and then Texas Theatre. The police would have been fully justified to kill Oswald in any of those instances with no questions asked. Instead CTers want us to believe that the DPD took Oswald into custody and freely allowed him to talk to the press and his family. They somehow convinced Jack Ruby, a loose cannon, to commit the murder on national TV and trusted him to remain silent while he spent the rest of his life in jail. Absurd. Ironically, the DPD got burned for trying to be as open and transparent with their treatment of Oswald as possible. As a result, they inadvertently created a security risk.
-
Only a sociopath would say that the police would have been justified to kill Oswald in the TSBD. For what, drinking a Coke?

Additionally... extreme doubt that it was actually Oswald that was present at the Tippit shooting.
At the Tex. Theater...things obviously did not really happen as the fable story says.
-
As stated in several other posts...Jack Ruby was allowed to declare his own actions for the entire weekend.
The Warren gang accepted without any doubt Mr Ruby's professed alibi despite contradictory statements and conflicting witness testimony.
Sorry about this..lone nut theorists :(

So hilarious in its logical inconsistency. Obviously, if the conspirators were framing Oswald and intended to silence him at the TSBD, their story would not have been that he was "drinking" a coke. HA HA HA. Their story would have been something that allowed them to use lethal force. For example, that they encountered Oswald trying to escape with a gun. The point being that, if there was a conspiracy that included a plan to silence Oswald, they could have made up whatever scenario was necessary to do away with him while he was out of sight in the building. No one would have been the wiser. In fact, that is actually what the contrarians suggest the police did do at the TT including planting a gun on Oswald! But the DPD still didn't kill Oswald given this golden opportunity!!! Unreal. Thus, our contrarians have inadvertently demonstrated, once again, that there was no conspiracy.
-
When was Oswald ever out of sight in the building after the police arrived?
-
You are apparently unaware that a review of Ruby's polygraph shows that he arguably actually failed the question about whether he was involved in a conspiracy with Oswald. The HSCA polygraph experts stated the following in their report regarding the reaction to the question, "Did you assist Oswald in the assassination?":
In fact, the reactions to the preceding question--(Did you assist Oswald in the assassination?)--showed the largest valid GSR reaction in test series No. 1. In addition, there is a constant suppression of breathing and a rise in blood pressure at the time of this crucial relevant question. From this test, it appeared to the panel that Ruby was possibly lying when answering "no" to the question, "Did you assist Oswald in the assassination?" This is contrary to Herndon's opinion that Ruby was truthful when answering that question. (8 HSCA 217-218)
You are also apparently unaware that Ruby later admitted that his tale about shooting Oswald to spare Jackie a trial was false.
Your bizarre scenario requires one to believe that every DPD officer was in on the plot and that therefore it would have been an easy task to kill Oswald much earlier. But no one argues such a silly scenario. Most DPD officers were not in on the plot.
Also, when did the DPD allow Oswald to "freely talk to the press"? When was this? Not on this planet. The DPD allowed Oswald to have very little interaction with the press. All of his comments to the press combined lasted less than 3 minutes.
The DPD also, in clear violation of the law, refused Oswald the right to have an attorney present during his questioning. Gee, why was that?
The DPD also failed to record a single one of Oswald's numerous interrogation sessions. Gee, why was that? This was the most important, historic suspect ever in DPD custody, but they never managed to record a single one of his interrogations.
There's also the fact that Ruby clearly entered the basement with help from someone inside the basement. The tale that he strolled down the Main Street ramp was debunked years ago. Even the HSCA rejected it and acknowledged that someone on the inside let Ruby enter the basement.
Finally, lone-gunman theorists still have no credible innocent explanation for all of Ruby's numerous long-distance calls to Mafia contacts in the weeks leading up to the assassination.

Commonsense would reveal that if the plot to murder JFK was as wide spread as Mr "Smith" proposes then there would not have been an assassination....Because it would not have been a secret....

Ruby "arguably actually failed" a polygraph? Wow. I guess that really does it. Again, there would be no need for Jack Ruby in a conspiracy that involved killing Oswald. There were multiple opportunities before his arrest. And the DPD freely allowed him to speak to the press in the hallways and even at a press conference full of reporters and TV cameras. He also was allowed to speak with his own family. It's absurd to believe they somehow recruited a loose cannon like Ruby and then trusted him to remain silent for the rest of his live in prison.

And then there's the testimony of Julia Ann Mercer, the wife of a U.S. Congressman. Like many witnesses, Mrs. Mercer later discovered that the FBI had brazenly misrepresented what she had said during her FBI interview. Mrs. Mercer corrected the FBI's distortion when she spoke with Jim Garrison's staff. At first, Garrison didn't believe her because, at that point, he didn't believe that FBI agents would misreport an interview and forge a signature, but Mrs. Mercer and her husband proved that the signature on the FBI interview report was not hers.
Mercer said she saw Jack Ruby driving a truck in Dealey Plaza about 90 minutes before the assassination, and that another man exited the back of the truck carrying what appeared to be a rifle case, walked up the grassy knoll, and did not return to the truck.
This is essentially the same account that she gave to the Dallas County Sheriff's Department shortly after the assassination. She didn't mention Jack Ruby because she didn't know who he was at that point. She mentioned the truck and mentioned seeing a man carrying a gun case get out of the truck and walk up the grassy knoll.
In her discussion with Garrison staffers, Mrs. Mercer related the following:
On Saturday 23 November, she had positively identified a photograph as that of the man in the driver’s seat of the pick–up truck. She had turned the photograph over and saw Jack Ruby’s name written on the back.
After seeing Ruby murder Oswald on television, she contacted the FBI and told them that Ruby had been the man sitting in the pick–up.

I was thinking the same thing. Why didn't Baker just shoot him when he saw Oswald?
Only a sociopath would say that the police would have been justified to kill Oswald in the TSBD. For what, drinking a Coke?

And, lo and behold, who came to visit Jack Ruby soon after he was jailed for shooting Oswald? Joseph Campisi, the number 2 Mafia guy in Dallas and a lieutenant in the Marcello crime empire. Just an innocent social visit, right?
Of course, the HSCA found that Sam and Joe Campisi since 1947, and had been seen with them on many occasions.
Also, we know from released HSCA files, that Gerry Patrick Hemming, a CIA asset, told the HSCA that he saw Ruby in Cuba in late 1959, and that Ruby sold jeeps to the Cuban Air Force (https://www.history-matters.com/archive/jfk/hsca/unpub_testimony/pdf/Hemming_3-21-78.pdf).
Hemming added that he saw Guy Banister and George DeMohrenschildt at a meeting of anti-Castro operatives in mid-1962 (Ibid.).
Hemming also revealed that after Castro took over in Cuba, he saw Oswald in the Cuban Consulate in Monterey Park, CA. He said Oswald seemed to
know a lot about Hemming's background, and this made Hemming suspicious. On another occasion, said Hemming, he encountered Oswald in late 1962, and that Oswald had been trying to infiltrate Hemming's group at the motel where they were being detained (Ibid.)

Joseph Campisi, the number 2 Mafia guy in Dallas
Who was #1?

It should be noted that the smoking gun Lafitte datebook mentions Ruby and indicates he was part of the assassination conspiracy. Hank Albarelli's bombshell new book Coup in Dallas discusses this fact and provides the most thorough analysis of Ruby I've ever read.
-
If anything, the involvement of Jack Ruby is indictive of no conspiracy.
Indicative of no conspiracy? No it isn't. That's silly.
for the DPD to kill Oswald
the DPD still didn't kill Oswald given this golden opportunity
This idea that the Dallas Police operated as some kind of Borg Collective doesn't fly.
Most cops just do like they're told. Most genuinely thought that Oswald was the shooter.
It's absurd to believe they somehow recruited a loose cannon like Ruby and then trusted him to remain silent for the rest of his live in prison.
Ruby didn't live very long. Joe Valachi lasted a lot longer.
-
I don't think Ruby was anyone's first choice for a hitman but once Oswald was in police custody, Ruby was one of the few mafia-connected people who could easily slip into and out of police headquarters in Dallas.
-
Ruby's involvement lends itself more to the absence of a conspiracy. The fantasy conspirators would have to recruit someone to kill Oswald in front of numerous police officers and a national TV audience and face the rest of his life in prison. And then trust this screwball to remain silent forever. He shows up only seconds before Oswald gets in the car after running some meaningless errands and leaving his dog in the car. Good grief. This was the "plan" when the authorities had numerous golden opportunities to kill Oswald before he was arrested? No sensible person can believe such nonsense.

Good point , Jon..... And it seems that the DPD weren't protecting their suspect at all while Lee was in their custody...He was taken through the halls of the police station several times. ..... Almost inviting someone to do what Jack Ruby did.

Given Ruby's lifelong relationships with members of the mafia, his friendships with Dallas police officers, and his debts, he was perfect for that role.
He was expendable but knew enough about the mafia and Dallas PD corruption to keep his mouth shut in order to protect his family.

Jack Ruby had pushed for Earl Warren to take him back to Washington so he could tell the Warren Commission what was on his mind about the JFK Assassination and as everyone knows , Ruby was denied that request . I think that Ruby knew he was probably a dead man if he talked or not . I think Ruby would have died in jail or would have been killed maybe in a way that looked suspicious like several of the people who saw or heard something that might have tied them into a conspiracy .

As if Ruby's "explanation" makes any more sense.
And you're accusing Biden of having cognitive issues!
ROFL.
Remember that humans communicate best in complete thoughts not incoherent fragments. So start over using that premise (resist the temptation to use emojis or ROFL) and try to articulate a coherent point that can be used as a basis for discussion. You can do this.
Let me help get you started on the right track:
"I [don't get confused - this means you "Otto"] don't find Ruby's "explanation" [explain what is meant by this] to make any sense because [here you fill in your reason]. Instead I believe the plan of my fantasy conspirators was to allow Oswald to speak to the press, recruit someone to murder him and spend the rest of his life in jail, but only after running a meaningless errand and cutting down his opportunity to do so to seconds while leaving his dog in his car."
-
Why would a conversation be needed to point out that believing in Ruby's BS story indicate a cognitive problem?
Your past decade of compliance with any lie put forward by the WC shows I can't be too far off.
Let's have your next Biden moment!
Why are you so hostile? Now you are taking issue with trying to have a substantive conversation that does not involve personal insults etc. This is an endless pattern. Someone tries to have a sensible discussion about the case. You interject a lot of nonsense and attack the poster to derail the discussion. Repeat endlessly. Now you are baiting a political discussion here? Unreal. It's unfortunate that folks trying to have a discussion about the JFK assassination have to put up with this including frequent personal attacks and use of profanity.

OK, Mr "Smith"..... Let's have a sensible discussion about Lee Oswald telling Captain Fritz that he was in the first floor lunchroom when the president passed by the TSBD. And he told Fritz that he saw Junior Jarman and Harold Norman walke by the lunchroom as he sat there eating his lunch. Jarman told the investigators that he and Norman had in fact walked by that 1st floor lunchroom at about 12:26.
Do you not believe that mr "Smith" ?.....

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.

A crucial issue is how Ruby got into the DPD basement. The WC claimed Ruby walked down the Main Street ramp to enter the basement. Of course, if Ruby entered the basement another way, someone on the inside would have had to help him do so, which is why lone-gunman theorists continue to cling to the WC's tale about Ruby's entering the basement.
But several witnesses who were at or near the Main Street ramp before the shooting insisted Ruby did not go down it. Indeed, the policeman who was on duty at the top of the ramp vehemently denied Ruby had walked down it. The policeman said that no one walked down the ramp, and he volunteered for and then passed a lie-detector test to prove his veracity.
The HSCA reexamined the matter and concluded the evidence strongly indicated Ruby did not use the Main Street ramp, that he must have gotten into the basement through another entrance, and that he received help in doing so. The committee noted the several witnesses who were near or at the ramp who insisted Ruby did not use that entrance.
In fact, one of the witnesses was a UPI reporter, Terrance McGarry. McGarry said that at least five minutes before Oswald was shot, he had stationed himself at the middle of the basement end of the Main Street ramp and that no one came down the ramp during that time. Another one of the witnesses was taxi driver Harry Tasker, who knew Ruby. Tasker was standing at the ramp's entrance and kept the ramp under constant observation. Tasker told the FBI that not only did he not see Ruby walk down the ramp, but that he did not see Ruby anywhere near the ramp.
And let's remember that Dallas police sergeant Patrick Dean failed a lie detector test regarding his reassignment of police guards away from the elevators and a door to a stairway next to the stairs just before Ruby shot Oswald.
Yet, to this day, lone-gunman theorists claim Ruby entered the basement by walking down the Main Street ramp. Why? Because they know that if Ruby got into the heavily guarded basement by a different route, this would mean he lied about how he entered the basement and that someone on the inside let him in. This, of course, would prove that Ruby's shooting of Oswald was not a spontaneous act but rather a premeditated killing to silence Oswald.

Ruby was apparently quite chummy with the guys down at the DPD. Because someone let him in doesn't mean that whoever did that was also part of the conspiracy.
