A new study has been commissioned by Professor Larry Sabato and conducted by a private firm, Sonalysts. The study, released this week, says unequivocally that the sound of gunfire on November 22, 1963, was not recorded and that the House Select Committee on Assassinations (HSCA) was wrong to use acoustic evidence to support its findings of conspiracy.
Key findings include:
* The recording that Sonalysts studied were copied from the original Dallas Police Department (DPD ) recordings:
Sonalysts: “the recording we studied originates from the same source as those studied by previous researchers. Differences, where they are noted, appear to arise solely from mechanical defects in the recording medium, e.g. skips.”
* The motorcycle with an open microphone was traveling at a high rate of speed at the time of the assassination, indicating that it was not in the presidential motorcade:
Sonalysts: “The extracted data suggest the movement of the motorcycle in this time period is along an unimpeded route at constant high speed with no evidence of slowing for turns, as would be expected if the motorcycle was part of the motorcade.”
