Joe. I've attempted to point this fact out to Tony based on Myers work, which supports the same iron clad video evidence that there is no way McLain could be where he is required to be for this acoustic evidence to hold merit. He is not having it and just says everybody is lying.

Paul Seaton's website is longer than it needs to be, but it's clear from looking at it that no motorcycle is near the location it has to be, as required by the HSCA acoustic study.

LoginThe scientists who made the original acoustic study declared three things, all of which they were quite certain of:
1. There were 4 shots.
2. They could tell, based on the acoustic signal, where the shots came from, three from the TSBD-SN, and one from the Grassy Knoll. They were certain the shots were within ten feet of these locations.
3. They could also tell, based on the acoustic signal, the location of the microphone that picked up the sound of the gunshots, from around the corner of Houston and Elm streets. Clearly, a motorcycle with the stuck microphone was rounding this corner at the time, picking up the first shot while still on Houston Street and the last shot on Elm Street. So they drew 4 "acoustic circles" on a map, each with a diameter of 20 feet.
The scientists even explicitly stated that there theory can be verified, or falsified, by studying films and photographs, made at the time of the shooting. At each shot, there should be a motorcycle within the corresponding acoustic circle.
If the film showed a motorcycle at that corner, their theory would be supported. If there was no motorcycle, their theory would be proven wrong.

The problem with the acoustic study, is that there were not motorcycles everywhere. There were four motorcycles just behind the first car, the Presidential limousine. Then, there was a big gap with no motorcycles. The next pair of motorcycles was between the ninth and tenth car, just ahead of "Congressman's Car #1", ridden by Officer McLain and Baker.
And the Robert Hughes film shows Officer McLain in this position. It shows the Presidential limousine rounding Houston and Elm, followed by the other vehicles. Not until the fourth car, LBJ's yellow car, starts rounding the corner of Houston and Elm, does Officer McLain's motorcycle come into view, rounding the corner of Main and Houston.
When Robert Hughes's camera is stopped, the time is equivalent to z160. We can tell this from the Zapruder 160 frame, which shows LBJ's yellow car just starting the turn onto Elm Street. The latest the first shot could have been fired, according to the acoustic study, is z175. And we can see Officer McLain just come into view, at the corner of Main and Houston.
As Robert Hughes shuts off his camera, Officer McLain has the length of that block of Houston Street to travel, he has to go about 180 feet, and has just under a second, to get within that ten foot circle that the acoustic scientists predicted a motorcycle would be in. Clearly impossible.
Officer McLain has to average 153 MPH during the next second to reach the first ten foot acoustic circle, 180 feet away. Beyond impossible. Not even close.
