# JFK was killed by a conspiracy, not a lone gunman

**No verdict.** An official congressional committee concluded a conspiracy was probable, but its key evidence was later discredited, and no plot has ever been substantiated. The physical evidence points to Oswald.

## Summary
The most investigated murder in history, and the one most Americans still believe was a conspiracy. The physical evidence points to a lone gunman; the doubts have never fully closed, and we do not close them here.

## The claim
That President John F. Kennedy was killed not by a lone gunman but as the result of a conspiracy (variously attributed to the CIA, the Mafia, anti-Castro Cubans or others) that was then covered up.

## Origin and timeline
- Nov 1963: Kennedy is shot in Dallas; Lee Harvey Oswald is arrested, then shot dead two days later by nightclub owner Jack Ruby before any trial.
- 1964: The Warren Commission concludes Oswald acted alone, firing three shots from the Texas School Book Depository.
- 1979: The House Select Committee on Assassinations concludes Kennedy was 'probably' killed by a conspiracy, citing disputed acoustic evidence.
- 1982: A National Academy of Sciences panel finds that acoustic evidence does not hold up, undercutting the official conspiracy finding.

## The evidence, claim by claim
- Claim: One bullet could not have wounded two men so many times.
  Evidence: The 'single bullet' looks impossible only with the men lined up directly front-to-back. Correctly reconstructed (Connally sat lower and inboard) the trajectory lines up, and modern 3D analyses support it.
- Claim: Official acoustic evidence proved a second gunman.
  Evidence: That evidence was the basis for the 1979 'probable conspiracy' finding, and a 1982 National Academy of Sciences panel showed the sounds were recorded about a minute after the shooting, from the wrong place.
- Claim: Killing Oswald before trial was silencing a witness.
  Evidence: It looks that way, but investigations found Ruby to be an unstable, impulsive man who reached the basement by chance; no evidence has ever tied his act to a wider plot.

## Why people believe it
- It feels intolerable that a president could be killed by a single ordinary man acting alone: the scale of the effect seems to demand a cause of equal size.
- The government really did seal records for decades, and genuine Cold War secrecy made every gap look like a hidden hand.
- Oswald was murdered before he could be tried, so the one person who could have answered never did.

## Open questions
- The Dictabelt recording behind the HSCA's conspiracy finding has never been fully resolved: a 1982 NAS panel found the sounds were recorded about a minute too late, but specialists have argued the acoustics back and forth in peer-reviewed journals ever since.
- The exact timing of the shots that hit Kennedy and Connally is still debated frame by frame; Connally himself testified under oath that he was hit by a separate bullet from the one that struck Kennedy first.
- Parts of the record are simply gone: the autopsy doctor admitted burning his original notes at home, and Kennedy's preserved brain was discovered missing from the National Archives in 1966 and has never been found.
- The Warren Commission and the HSCA are both official U.S. investigations, and their contradictory top-line conclusions (lone gunman versus probable conspiracy) have never been formally reconciled by any later government body.
