Forty-seven years ago today, President John F. Kennedy was shot and killed while riding in a motorcade through Dallas with his wife, Jacqueline, and Texas officials.

Sorry, there are so many things wrong with the Dictabelt theory.

The machine itself and how it operated, the timing compared to the Gray recording and the speed that was not a constant and changes the location of the shots compared to Zapruder.

The fact the Dictabelt records over itself without an erase feature, so any 'old data is still layered into the tape.

The placement of the 'open mike', that put the officer in question, H.B. McLain, at 120-140 feet from the President at the first shot, but Zapruder shows him at 250 feet or more.

The Dictabelt recording attributed to McLain's open mike also records a rising and falling siren. McLain was one of the officers escorting the limo to Parkland. His siren was blaring the entire time.

The sounds on the Dictabelt cannot be resolved to the photographic evidence of Zapruder. The timing is off anywhere the 'shots' are placed in reference to where McLain was positioned and where Zapruder shows the officer.

That in itself lends to disputation of the recording.

Erroneous conclusions based on subjective data, and the Dictabelt acoustic evidence is subjective, makes every conclusion after that incorrect.

“Erroneous conclusions based on subjective data....”

Essentially the basis for all of your strenuous objections to any challenge to the Warren Commission Report. You attribute your own arguments to third parties then quote yourself as an authority. Nice work.

Actually, confirmation of third party arguments is what scientific study is all about. It's called 'peer-review' in some cases.

In this circumstance the ability to repeat any test, or experiment is confirmed by outside analysis of that work.

The best thing any researcher can do is have a skeptical eye on ALL the information until it can be corroborated by experiment or data analysis of those experiments.
The best example I can give for that is the work of Bellesiles on firearms in colonial times. The anti-gun crowd was singing it's praises until peer-review illuminated the falsification of factual data.

Same thing applies to the Kennedy assassination. Take any point you want to consider, the rifle, the composition of the bullets available, the location, the position of the witnesses, and delve into proving or disproving the information. When one 'fact' cannot be confirmed or corroborated by other information relative to that 'fact', it has to be discarded as false.

I do not consider myself as any 'authority' only a presenter of facts confirmed by my own observations and experiments. That they corroborate the information available doesn't make them any less valid.
