Denise's Guide for Beginners
Prolific assassination researcher and writer Dr. Mantik (M.D., Ph.D, specializing in interpreting X-rays for cancer patients) has his JFK Assassination "Primer" for Beginners (See https://themantikview.org/pdf/JFK_Assassination_Paradoxes.pdf), focusing mainly on the medical cover-up. I thought I might create my own version, in order to provide a map for understanding some of my conclusions.

Orientation and Overview
On Friday, November 22, 1963, President John F. Kennedy (JFK) was shot and killed in Dallas, Texas. The place where this took place was Dealey Plaza, in downtown Dallas, along Elm Street between the corner of Houston and the railroad Triple Underpass. For the specifics of how the motorcade was set up, see http://jfk.hood.edu/Collection/Weisberg%20Subject%20Index%20Files/M%20Disk/Motorcade%20Route/Item%2015.pdf, but for our purposes, it's enough to know about a few key vehicles (the lead car, Presidential limousine, Secret Service Follow-up Car, Vice-)resident's car, and the Secret Service VP Follow-up Car) plus a few key people in those cars
Plus the shooter in the building, of course. For the sake of argument and convenience, we'll say it was Lee Harvey Oswald, although with the understanding that Oswald was never convicted of killing Kennedy in a court of law (he was only accused), and with the suspicion that at least some of the evidence used to convict him in the court of public opinion may have been manufactured.
There was a "Lead Car" driven by Dallas Police Chief Jesse Curry and containing Dallas County Sheriff Bill Decker and a couple of Secret Service men. After that car was the President's open limousine with three rows of seats, containing Secret Service driver William Greer, Secret Service Special Agent In Charge (SAIC) Roy Kellerman in the front row, Texas Governor John Connally and his wife seated in jump seats in the second row (Connally on the right), and Jackie Kennedy and the President seated on the somewhat raised back seat (Kennedy behind Connally). Kennedy was killed and Connally was seriously wounded during the shooting. (Another victim who received minor wounds from a missed shot was bystander James Tague). The vehicle was modified from its original factory specs to put a "grab bar" railing across the top between the front row passengers and middle row area--which incidentally made it more difficult for agents riding in the front to climb into the back in case of an emergency--and to include two steps with hand-holds at the back of the car where Secret Service agents could stand and ride, as they were needed and travel conditions permitted. It is a point of controversy that no agent was riding on the back of the limousine at the time when the shooting began.
Behind Kennedy's limousine was the Secret Service Follow-up Car, which was of the same make and model as the President's limousine, but with different modifications. Running boards had been added with hand holds, such that four agents could stand on the running boards (two on either side) and hold onto the hand holds. One of those agents was Clint Hill, assigned to protect Jackie, who during the shooting, jumped off the running board, ran to the back of the limousine, pushed Jackie (who had started to crawl out onto the trunk of the car) back into her seat, and then climbed to the back seat to cover the first couple with his body. The car was driven by Secret Service driver Sam Kinney. Next to Kinney in the front passenger side was Assistant to the Special Agent in Charge (SAIC) Emory Roberts, who was in direct command of the Follow-up Car agents. Two of Kennedy's aides were in the jump seats in the middle row, and two agents were on the back seat. One of the agents on the back seat on the driver's side was forty-year-old and four-months-new to the Secret Service Special Agent George Hickey. Hickey's job at that time was to keep a general eye out for trouble and man the new state-of-the-art AR-15 rifle that was loaded and waiting on the floor of the follow-up car between him and his fellow Secret Service agent on the back seat seated on the passenger side. Neither man likely knew that the weapon they were ordered to man had a major flaw: the firing pin was too heavy, making it prone to incidents of unintended "slam fire" discharge.
It's important to note that about half of the agents in the follow-up car had been out late drinking the night before and into the early morning hours of the day of the assassination. Most of these agents admitted to having 1-2 drinks, claiming that they had been in search of food, but one of the managers of one of the places where they had been drinking claimed that the agents were "bombed." Syndicated Washington columnist Drew Pearson described the drinking incident in a column that caused some considerable embarrassment for the Secret Service, but the incident was minimized in the Warren Commission's report. It's important to note that Hickey was not among the agents who were out drinking, not even being in Fort Worth at the time. He was apparently well-rested and alert, having gone ahead to Dallas to help take care of the cars to make sure they were ready for the next day's motorcade and then gone straight to his hotel room, and to bed.
Behind the President's Secret Service Follow-up Car was the Vice-President's open convertible, driven by a Texas Highway Patrol officer, with Secret Service agent Rufus Youngblood riding on the passenger side next to him. In the back seat was Vice President Lyndon Johnson (behind Youngblood), Senator Ralph Yarborough, who was an important witness and seated on the driver's side, and Lady Bird Johnson sandwiched between the two men.
The next car was the Vice President's Secret Service Follow-Up Car, The driver was another Texas Highway Patrolman. Next to the passenger door was Special Agent in Charge (SAIC) Jerry Kivett. Between them on the front seat was Johnson Aide Clifton Carter. In the back seat behind the driver was Secret Service Agent Warren Taylor. Across the seat from him behind Civet was Secret Service Agent Lem Johns. I believe that there was a third agent sandwiched between them, but that is a subject for another time.
After this car came the rest of the motorcade, beginning with the mayor's open convertible car and then some news cars. The mayor's wife, riding in this car, became an important gun smoke witness.
The motorcade traveled from Love Field, where the President's plane had landed, into downtown Dallas. It moved west along Main Street, made a 90º right-hand turn to travel north on Houston Street for a short block. The President's car was now in Dealey Plaza. Almost dead ahead, just to the left of the next intersection, was a red brick building called the Texas School Book Depository (TSBD), a warehouse for textbooks that would be sent to public schools in Texas. Immediately in front of the building was a small access road, called the Elm Street Extension. In front of that was Elm Street proper. The turn onto the access road was a 90º left-hand turn, but the motorcade would make the harder 120º left-hand turn to travel southwest onto Elm Street proper, which was a somewhat curved "S" shaped road leading to a railroad underpass known as the Triple Underpass. Beyond the Triple Underpass was the access to Stemmons Freeway, the highway that would take the motorcade to its planned destination of the Trade Mart, where Kennedy was preparing to give a speech.

From a different perspective:
Inside the TSBD building, a man with a gun was waiting. For the sake of argument, we'll say it was Lee Harvey Oswald. Oswald was accused of the crime of killing Kennedy, although Oswald was never convicted in a court of law. He was himself murdered 2 days after Kennedy died.
The Investigative Bodies
To start, let's take a look at some of the investigative bodies that have dealt with the JFK assassination over the decades, and why their conclusions have been so unsatisfactory.
To start, let's take a look at some of the investigative bodies that have dealt with the JFK assassination over the decades, and why their conclusions have been so unsatisfactory.
- The Dallas Police Department (DPD) & Dallas Sheriff's Department were the first investigative agencies on the scene of the assassination and the Tippit Murder Scene were the Dallas Police Department. They're the ones who sealed off and searched the building, and found the gun and the shells in the 6th floor of the building. The Sheriff's Department took witness statements. But by the end of the weekend, any investigation they had started would be taken over by federal investigators.
- The State of Texas murder inquiry would have begun with an autopsy of the President's body performed by Parkland pathologist Dr. Earl Rose. However, Secret Service agents removed the body from Parkland hospital despite Dr. Rose's protests, thus breaking the law.
- The Federal Bureau of Investigation (FBI) and the Secret Service (SS) had their own investigations occurring from the beginning, as well. But by the Monday following the assassination, any local investigations were coopted by the FBI who, along with Secret Service agents, had been investigating things in Dealey Plaza, Parkland Hospital, and even participating in the questioning of Oswald. The SS collected pictures and films from bystanders, the FBI collected ballistic evidence from Parkland Hospital, and were involved in numerous other investigative activities. Many of the witness interrogation were attended by agents from both the FBI and SS, such as the questioning of Parkland employees. There should be standard "302" (name of the FBI reporting form) reports on all witness statements they collected, but some of those appear to be nonexistent. Others can be found online, e.g., by clicking on specific witness names at https://www.history-matters.com/analysis/witness/.

When Things Changed
The situation took a drastic turn after Oswald was murdered on live TV by nightclub owner Jack Ruby, who was rumored to have ties with Organized Crime, a mere 2 days after Kennedy was killed.

The famous Pulitzer-prize winning photograph of Jack Ruby shooting Oswald in front of Press cameras.
With Oswald dead, there would be no trial. Oswald never admitted to killing Kennedy privately, much less on camera. Ruby went on trial, but for the crime of killing Oswald, not Kennedy. Unlike the "Did Oswald do it?" debate that has been going on among researchers for decades, there was really no question about who shot Oswald. Obviously, Ruby did it. Researchers have debated Ruby's motive in doing so for decades, although Ruby himself said something about wanting to become a sort of "hero" by killing the man who killed Kennedy, and not wanting Kennedy's widow to have to relive the horrors of the assassination by having to come to Texas to testify. There has been some speculation and evidence suggesting a prior relationship between Oswald and Ruby prior to the assassination, and a lot of research into some very interesting potential Oswald-CIA connections, but those are beyond the scope of this author's work. I can't speak at all to Oswald's motives. There has even been some speculation that he didn't want to shoot Kennedy at all, but was trying to hit Governor Connally (for whom he might have had a motive in wanting to shoot due to Connally's refusal, when he was Secretary of the Navy, to reconsider the "Dishonorable Discharge" that Oswald's marine discharge was changed to after Oswald defected to the Soviet Union), and missed, due to some combination of Oswald's less-than-stellar marksmanship and his cheap mail-order gun with its misaligned scope). I can't even say with absolute certainty that it was Oswald who was the TSBD shooter. I think it was, but I can't say it with total conviction.
I can say with total conviction that most of the problems related to the anomalies in the medical evidence and why no single story was ever settled on as the explanation for what happened was because there was a cover-up of the Secret Service FUBAR (F***ed Up Beyond All Recognition) response to the shooter in the TSBD window. I can explain what happened in Dealey Plaza, and why the medical evidence, picture evidence, and film evidence has been so paradoxical. As far as I know, I am the only researcher who can explain all this. But I have my limits, and unraveling the motives behind Oswald (assuming he was the TSBD shooter) and Ruby are beyond my capabilities.
But I do know the point at which the "investigations" became less about finding out what really happened (I think the investigators knew what had happened, by that point) and more about "convincing the Public" that Oswald was the "lone nut" shooter. I am not the first researcher to recognize the point when this occurred, but I am, I think, the first to explain why it occurred.
The point of change, of course, is when Oswald was killed.
The reason we know this is because of FBI Director J. Edgar Hoover and Deputy Attorney General Nicholas Katzenbach.

Deputy Attorney General Nicholas Katzenbach sent this memo on November 25, the day after Oswald was killed and the same day as Kennedy's funeral. It outlines what eventually happened: the appointment of a Presidential Commission in order to "head off public speculation or Congressional hearings of the wrong sort":

What are "Congressional hearings of the wrong sort?" The sort that would be interested in truth?
But note that this Commission would rely heavily on the FBI's report of events.
But the FBI's report was flawed. According to the "Visual Aid" brochure of pictures of an FBI model of Dealey Plaza, this 3-shot scenario was apparently their explanation for what happened:
But note that this Commission would rely heavily on the FBI's report of events.
But the FBI's report was flawed. According to the "Visual Aid" brochure of pictures of an FBI model of Dealey Plaza, this 3-shot scenario was apparently their explanation for what happened:
Their "first" shot limousine position is about the position of the limousine in the famous Altgens 6 photograph. In that image, Kennedy is clearly already in distress. His hands are already in his "chest grab" position, and Jackie's hands are on his arm. She testified that she was looking to her left until she heard the shot, then turned to look at her husband. JFK was clearly shot at some point before their "Shot One."
Their "third" shot position is extremely odd. It doesn't match the limousine's position for the Zapruder film head shot. (It is, however, what I believe to be the limousine's correct position for the head shot.) Speaking of the Zapruder film, there is a growing body of evidence--and a growing number of researchers who believe--that the Z-film has been altered from what it originally showed. I am one of those who believe it has been extensively altered--not only via frame removal to take out an embarrassing stop of the limousine, thus explaining the impossibly fast head turns of driver William Greer and impossibly fast movement of Charles Brehm's son, etc., but to insert a fake "head shot" where one didn't actually occur--the real one occurring when the limousine was in the "Shot Three" position--and to perpetuate the fiction that "all" of the shots were fired "from behind." See my article at https://www.a-benign-conspiracy.com/zapruder-film-alteration.html
The other problem with the FBI's version of events, which was Kennedy hit with Shot One, Connally hit with Shot Two, and Kennedy hit with Shot 3 (a head shot) is that this scenario does not account for the minor wounding of spectator James Tague, who was standing by Main Street and the Triple Underpass and who was slightly injured by bullet fragments or cement fragments from a ricochet that struck the Main Street curb. There is same-day corroborating evidence for Tague's wounding, but the FBI never explained how that could have happened with only "three" shots.
Furthermore, there are problems in that more recent medical experts studying the X-rays have become convinced that there were two head shots, one coming from the front. Moreover, there is a problem of the trajectory of the head shot as entering the "EOP" location on Kennedy's head and exiting above the right ear, not matching where the vast majority of witnesses at Parkland Hospital (where doctors tried in vain to save Kennedy), or at the Bethesda autopsy described seeing the "blow-out hole!"
But I'm getting ahead of myself.
For now, just be aware that the FBI scenario does not fit other evidence. Nor do some pieces of evidence fit with other pieces of evidence. Nor do certain pieces of "evidence" fit with what the witnesses recalled. It's a conundrum that can only be solved by understanding that some of the evidence was fabricated or altered.
Who would have done such a thing? The answer is, the CIA.

The CIA's involvement
As I noted above, I cannot speak to the very interesting Oswald-CIA connections. I can, however, state with certainty that the CIA was "at the heart of a 'benign cover-up' at the spy agency, intended to keep the commission focused on 'what the Agency believed at the time was the "best truth"--that Lee Harvey Oswald, for as yet undetermined motives, had acted alone in killing John Kennedy."
CIA historian David Robarge found documents wherein there was an admittance that then-CIA director John McCone controlled information given to the Warren Commission and kept certain "incendiary" information from them.

All the talk about the "control of information to the Warren Commission" being about the CIA's clumsy attempts to kill Castro ("Operation Mongoose") was pure speculation on Roberge's part. He didn't know what information was being controlled, only that information was being controlled. But thanks to the work of ARRB Analyst Doug Horne, we do know what that information was--at least in part. It was the Zapruder film. See Horne's article "The Two NPIC Zapruder Film Events: Signposts Pointing to the Film's Alteration" at https://www.lewrockwell.com/2012/05/douglas-p-horne/the-two-npic-zapruder-film-events-signposts-pointing-to-the-filmsalteration/ and other locations on the Web.
Buried in the CIA's website can be found a very interesting document outlining a cooperative "Agreement Between CIA and Secret Service." While this document explicitly says that there was no such agreement in force "at the moment," it is also clear that there the "most recently" signed cooperative agreement was signed in 1971, strongly implying that such an agreement had been signed before 1971--say, in 1963. A triggering event for such an agreement is "death of a President." There is only one President whose death would have triggered such a cooperation agreement: the death of President John F. Kennedy.
