The official record of John F. Kennedy's assassination is not a single, unchanged conclusion. Its disagreements need to be explained rather than erased, particularly when claims leap from intelligence failures to an allegation that an agency ordered the killing.
The Warren Commission concluded in 1964 that Lee Harvey Oswald acted alone. Its report also identified shortcomings in presidential protection. A finding of inadequate protection is a different proposition from a finding that protectors organised the crime.
In 1979 the House Select Committee on Assassinations reached a qualified probable-conspiracy conclusion. Its summary cited acoustic evidence suggesting two gunmen, while saying it could not identify the other gunman or determine the conspiracy's extent. It separately concluded that the Secret Service, FBI and CIA were not involved, although it criticised aspects of their performance and information sharing.
The acoustic premise did not go unchallenged. The National Research Council's 1982 review concluded that impulses interpreted as shots had been recorded about a minute after the assassination. It found no reliable acoustic support for a second gunman. Timing matters: even a sound resembling gunfire cannot locate an assassin if it belongs to a different moment.
These distinctions prevent two opposite distortions. It is inaccurate to say every official inquiry simply found no possible conspiracy. It is also inaccurate to present the House committee's qualified finding as proof that a named federal agency directed the murder.
An archive preserves investigative leads, claims and findings; their presence in a released collection does not make them equivalent. Neither the Warren Commission nor the House committee established an agency-directed assassination. Their criticisms of protection and investigation remain consequential without being recast as findings that officials ordered the murder.
