Tape of Kennedy Killing receiving digital analysis



Should be interesting stuff. The current state of the argument between D.B. Thomas and his critics is whether the sound recording did, in fact, capture sounds from the plaza during the relevant time at all, with Thomas taking the affirmative. According to Thomas, there were four shots, two hits. The single bullet theory works. The fatal head shot was from the front. Thomas wrote the last peer reviewed article on the matter (the gentleman who chaired the National Academy of Sciences in 1982, who wrote the report attacking the acoustics evidence, is said to be preparing his own paper on Thomas's work, but I don't think it's come out yet). His critics have attacked him on television with tests purporting to show that the impulses on the dictabelt are from a motorcycle parked at the Dallas Trade Mart, five minutes from Dealey Plaza.

The tests will show:

A) The impulses on the dictabelt are gunshots, and from the echo patterns we determine that the shots all came from the right rear of the microphone (and therefore, the right rear of Kennedy's car).

B) The impulses on the dictabelt are gunshots, and from the echo patterns we determine that some shots came from the right rear of the microphone, while others originated from the right front.

C) The impulses on the dictabelt are not gunshots but some other kind of background noise irrelevant to events in Dealey Plaza.

A and B are answers which would pretty much seal things up one way or the other. C would obviously leave us largely where we are now, with dueling explanations and uncertainty (the House Committee's reinterpretation of the evidence was prompted by the acoustics evidence, but their subsequent investigations led them to additional leads that further encouraged the idea of a conspiracy). I'll be waiting to hear their results, and look forward to seeing how each side evaluates their findings.
