sandbox  Solving the biggest mystery in history 

The biggest mystery in history is littered with official evidence and information that conflicts with other information provided by witnesses and other sources. In a normal situation, there may be some disagreement between official and unofficial information but in this case, there seems to be disagreement as deep as a researcher wants to look. The mystery, of course, is the assassination of President John F. Kennedy on November 22, 1963.

The Warren Commission that was conducted at the request of succeeding President Lyndon Johnson, determined that lone shooter Lee Harvey Oswald was guilty and that he killed President Kennedy by firing three shots and that there was no evidence of a conspiracy. There were several other inquires and a significant number of articles and books that questioned this finding in the following years but not until the late 1970's did an official inquiry cast serious doubt on the Warren Commission finding of only a lone assassin.

The House Select Committee on Assassinations was formed to review not only the assassination of President Kennedy but it also reviewed other shocking events from the 1960's. Polls showed the public had serious doubts about the government's investigations and the HSCA was tasked to address these conflicts. In the assassination of President Kennedy, the HSCA was completing it's work and drafts of the final report basically agreed with the findings of the Warren Commission that lone shooter Lee Harvey Oswald had acted alone in killing President Kennedy. But that finding was cast into doubt when an audio recording of the Dallas police radio channel was being reviewed by audio experts found that the acoustical "fingerprints" of gunfire were found on the recording. Because the HSCA audio experts identified the possibility that more than three shots were fired, the US Justice Department asked for other reviews of the audio analysis. Other reviews generally contended the audio analysis was not valid but none of those reviews attacked the HSCA audio analysis on the basis of the technique the HSCA used to analyze the audio, the skeptics used an instance of cross talk for example that indicated the shot like echo patterns occurred after the shooting was over and therefore were not valid.

The HSCA's audio experts were prevented from doing further studies which were necessary because the first shooting experiment in Dealey Plaza had microphones placed down Houston on to the turn to Elm Street at a spacing that would only determine the approximate location of the police motorcycle that apparently recorded it. After preliminary reviews, it was found that the echo patterns generally matched test shot echo patterns from either of the two locations test shots were fired from: 1. The Texas School Book Depository (TSBD) 2. The grassy knoll.
