Introduction to the JFK Assassination

Rob Attar opens the episode by recounting the pivotal moment on November 22, 1963, when U.S. President John F. Kennedy was assassinated in Dallas. Lee Harvey Oswald, a U.S. Marine veteran, was arrested for the murder but was killed two days later by Jack Ruby before he could stand trial. The 1964 Warren Commission concluded that Oswald acted alone, a finding that has been contested over the decades, leading to widespread belief in conspiracy theories.

Gerald Posner's Findings and Conclusion [02:06 - 03:49]

Gerald Posner, renowned investigative journalist and author of "Case Closed," asserts that Lee Harvey Oswald was the sole assassin responsible for JFK's death.

"I think that a single assassin, Lee Harvey Oswald, armed with a relatively cheap rifle, managed to kill John Kennedy and end his presidency all on his own, without any conspiracy."
— Gerald Posner [02:06]

Posner explains his extensive research, including interviews with hundreds of individuals and consultations with ballistics and forensic experts. Initially skeptical, his investigation led him to firmly believe in Oswald's solitary involvement. Even his publisher, Harry Evans, initially doubted but was eventually convinced by Posner's new evidence.

Exploring Popular Conspiracy Theories [05:27 - 09:36]

Posner outlines several prevailing conspiracy theories surrounding JFK's assassination:

1. Soviet or Cuban Involvement: Oswald's defection to the Soviet Union and his support for Fidel Castro fueled speculations that he acted on behalf of these nations.
2. Government Agencies: The CIA and FBI are often cited as potential conspirators, with theories suggesting that elements within these agencies sought to eliminate Kennedy due to his policies on Vietnam and potential disbandment of the CIA.
3. The Mafia: Kennedy's administration, particularly Attorney General Bobby Kennedy, aggressively pursued Mafia interests, leading to suspicions of Mafia involvement in the assassination.

Posner distinguishes between theories that suggest Oswald was a mere tool for these groups and those proposing the existence of additional shooters.

"There are two possibilities here. On the one hand, Oswald... he's been set up for the crime... On the other hand, he was part of a plot... he would never have made it out alive."
— Gerald Posner [06:57]

He emphasizes the lack of credible evidence supporting the presence of another shooter or a coordinated conspiracy.

Analyzing the Dealey Plaza Assassination Mechanics [09:54 - 13:36]

Posner breaks down the technical aspects of the assassination, addressing common arguments about the improbability of Oswald's success given his rifle's limitations and the President's movement within the limousine.

"One out of three shots is the shot that works for the assassin. It just gets in."
— Gerald Posner [09:36]

He details the three shots fired by Oswald:

1. The first shot missed, deflected by trees, and wounded a bystander.
2. The second shot hit Kennedy and Governor Connally but was non-fatal.
3. The third shot was fatal, striking Kennedy's head.

Posner argues that while chance played a role, Oswald's actions and timing were sufficient for the assassination to occur as recorded.

Debunking the "Magic Bullet" Theory [13:56 - 17:18]

Addressing the infamous "magic bullet" — a single bullet said to have caused multiple wounds to both Kennedy and Connally — Posner defends its plausibility:

"There is ballistic evidence that that bullet wasn't so magical."
— Gerald Posner [13:56]

He references ballistics experts who replicated the bullet's trajectory and condition, affirming that the single bullet theory holds up under scientific scrutiny. Posner clarifies that validating the single bullet does not inherently rule out conspiracy theories; it simply addresses one component of the assassination narrative.

The Zapruder Film and Its Interpretation [17:31 - 23:14]

The Zapruder film, a crucial visual record of the assassination, has been a focal point for conspiracy theorists who interpret it as evidence of a front shooter. Posner counters this by explaining the film's details:

"The President goes back in the opposite direction. The car is starting to zoom out of TD Plaza..."
— Gerald Posner [17:31]

Upon analyzing the film frame by frame, Posner concludes that the reactions captured are consistent with a rear shooter. He dismisses claims of tampering and underscores that the film, when properly examined, supports the lone assassin theory.

Acoustic Evidence and Its Rejection [23:14 - 27:57]

Posner critiques the acoustic analysis conducted by the House Select Committee on Assassinations, which initially suggested four shots were fired. Later reviews by the National Academy of Sciences disproved these findings, revealing that the audio evidence was misinterpreted.

"What tells me what happened is the autopsy X rays and photos. When I examine those with the medical examiners... shows wounds that came from the rear."
— Gerald Posner [23:22]

He emphasizes the importance of reliable evidence over popular but flawed acoustic studies.

Lee Harvey Oswald's Background and Motives [28:12 - 35:22]

Posner delves into Oswald’s early life, portraying him as a dysfunctional individual with a tumultuous history:

• Family Instability: Oswald had a strained relationship with his mother and faced bullying at school.
• Military Service: His time in the Marine Corps was marked by dissatisfaction and rumors of homosexuality, leading to his defection to the Soviet Union.
• Political Activities: Oswald's support for Castro and involvement in left-wing politics continued until his unsuccessful attempts to foster revolutionary support.

This background, according to Posner, culminated in Oswald's position at the Texas School Book Depository, setting the stage for the assassination.

"The Oswald that I know... could have been in the sixth floor of a building in downtown Moscow shooting at Nikita Khrushchev."
— Gerald Posner [28:12]

Jack Ruby and the Silencing of Oswald [35:22 - 55:40]

Jack Ruby's murder of Oswald is a critical event fueling conspiracy theories. Posner provides an in-depth analysis:

• Ruby's Behavior: Ruby, a local nightclub owner with a history of violence, had no prior connections to organized crime plots targeting Oswald.
• Opportunity Over Plot: Ruby killed Oswald spontaneously during transport, not as part of a calculated conspiracy.
• Public Reaction: Immediate public support for Ruby's actions, as evidenced by spontaneous applause and cheers, suggests his motive was personal grief rather than external coercion.

"It's an opportunity that presents itself to a guy who thinks people are going to clap him on the back and say... Thank you, Jack, for erasing the stain from Dallas."
— Gerald Posner [42:39]

Posner argues that Ruby's actions were not part of a broader conspiracy but rather the impulsive response of an individual disturbed by the assassination.

Shifting Public Opinion and Enduring Conspiracies [50:18 - 55:58]

Posner examines how public trust eroded over time, exacerbating belief in conspiracies:

• Warren Commission and Distrust: The comprehensive yet controversial Warren Commission report failed to quell skepticism, especially amid other governmental scandals like Watergate.
• Jim Garrison’s Investigation: District Attorney Jim Garrison’s flawed prosecution in New Orleans added fuel to conspiracy believers, despite lacking credible evidence.
• Cultural Influence: Oliver Stone’s film "JFK" dramatically influenced public perception, presenting compelling albeit historically inaccurate narratives that reinforced conspiracy beliefs.

"People think that everything Oswald did was part of a CIA plot... But there's no evidence of that, no credible evidence."
— Gerald Posner [35:22]

Persistence of Conspiracy Theories Today [55:58 - 67:02]

Despite Posner's exhaustive research debunking conspiracy theories, a significant portion of the American public remains skeptical of the lone assassin narrative. Factors contributing to this enduring skepticism include:

1. Government Secrecy: Ongoing classification of documents fosters distrust, leading people to believe in hidden truths.
2. Cultural Narratives: Media portrayals and the dramatization of the assassination perpetuate doubt.
3. Psychological Comfort: Complex and shadowy explanations provide a sense of meaning behind the trauma of losing a charismatic leader.

"If there are only 10 documents left, they'd be saying they must be hiding the real truth."
— Gerald Posner [55:58]

Posner remains steadfast in his conclusion that Oswald acted alone, awaiting any credible evidence that might contradict his findings. He critiques the public's reliance on incomplete information and the tendency to seek elaborate explanations for significant events.
