On November 22, 1963, President John F. Kennedy was shot in Dallas. The official investigation concluded that Lee Harvey Oswald acted alone. But conflicting evidence, a later government finding of 'probable conspiracy,' and decades of withheld files have kept the case from ever truly closing in the public mind.
Theories propose a broader plot — variously implicating organized crime, anti-Castro Cubans, elements of the CIA, or others — with a 'second shooter' on the grassy knoll. The core claim is that one man could not have done it alone.
Critics argue a single bullet could not have caused all the wounds; later reconstructions show the seating geometry makes it plausible.
The famous home movie shows the President's head motion, endlessly debated as evidence of a front shot.
A police dictabelt suggested a fourth shot to the 1979 committee — but acoustic experts later largely discredited it.
The Warren Commission's lone-gunman conclusion remains the official finding. The 1979 House finding of 'probable conspiracy' rested chiefly on acoustic evidence that subsequent analysis undercut. No investigation has produced a confirmed second shooter or a proven plot.
Skeptics of conspiracy note that physical and ballistic evidence is consistent with Oswald, that 'eyewitness' discrepancies are normal in chaos, and that no credible documentary proof of a wider plot has emerged in sixty years.
The persistent unknowns — Oswald's murky trip to Mexico City, intelligence-agency interest in him beforehand — are exactly what the newly released files speak to, without delivering a single decisive answer.
Where the file stands now
Following a January 2025 executive order, the National Archives released large tranches of previously withheld JFK records beginning March 18, 2025 — reportedly tens of thousands of pages, many fully unredacted for the first time. Historians who reviewed them found extensive new detail about Cold War CIA operations and surveillance of Oswald, but no document that overturns the basic lone-gunman conclusion or proves a wider plot.

The assassination reshaped American trust in government and inspired Oliver Stone's 'JFK,' countless books, and the enduring image of the grassy knoll.
