JFK Dictabelt Recording

And everybody is writing about how in Russia, people just fall from the windows of building and that is because of Putin and which is FAKE NEWS and propaganda, because Putin really dont have kill anyone, becuase there are no people´s election in Russia, but these assassinations are only in these democratic states and why these politicians must be killed, if the people elect good politician that dont please with rest of the top elite.

Of course "all the evidence is faked" maven Michael T. Griffith believes the long-debunked Dictabelt evidence!

Another one of your unserious, invalid, superficial replies. I have never said "all the evidence is faked." Where do you get that?

"Long-debunked dictabelt evidence"? Really? Who debunked it? The NRC panel? You know that not one of the NRC panel members was an acoustical scientist, right? Do you know anything about the new research that was done by several BBN acoustical scientists in 2020 that confirms the dictabelt was recorded in Dealey Plaza during the shooting? I bet you didn't even bother to read my article on the HSCA's acoustical evidence, which mentions this development. You seem to have no interest in objectively, seriously examining evidence that doesn't fit your minority view of the JFK case.

Let's review some of the evidence that supports the HSCA's finding that the dictabelt contains four gunshots that were recorded in Dealey Plaza during the assassination:

* At least four sets of gunshot impulse patterns with echo patterns unique to Dealey Plaza occur on the dictabelt recording. In other words, their acoustical fingerprints match those of some of the test shots fired in Dealey Plaza.

* Those echo patterns occur in the correct topographic order, which is an amazing correlation all by itself.

* Remarkable locational-movement correlations were found between the dictabelt gunshots and the test-firing gunshots. The BBN scientists determined that the probability that chance caused these correlations was “less than 1%.” Even the NRC/NAS/Ramsey panel admitted that their own calculations showed there was a 93% probability that the correlations were not the result of chance--a fact that is always ignored by critics who cite the panel's findings.

* The dictabelt contains N-waves from supersonic rifle fire, and those N-waves occur only among the identified gunshot impulse patterns, and only in the two impulse patterns that were recorded when the motorcycle’s microphone was in position to record them--yet another impressive correlation. The NRC panel didn't even mention this impressive item of evidence.

* Remarkably, the dictabelt not only contains N-waves but it also contains muzzle blasts and muzzle-blast echoes, and those N-waves, muzzle blasts, and muzzle-blast echoes occur in the correct order and interval, proving beyond any rational doubt that the dictabelt contains gunshot impulses. The NRC panel didn't address this remarkable evidence either.

* Windshield distortions occur in the dictabelt's gunshot impulse patterns when they should occur and do not occur when they should not, another stunning correlation. The HSCA arranged for a separate test to confirm the science and effects of windshield distortion. This is another impressive item of evidence that the NRC panel ignored.

* Mark Weiss and Ernest Aschkenasy, acoustical scientists from Queens College who specialized in processing acoustical signals for military applications, determined that gunshot impulse 144.9 (initially timed at 145.1) came from the grassy knoll. Weiss and Aschkenasy calculated there was no more than a 5.3% probability (P=0.053) that the 144.9 impulse pattern was not caused by gunfire, and they argued that the probability was likely lower than that. This is why they reported there was a 95% probability or higher that this shot came from the grassy knoll.

In another oblique admission, the NRC/NAS/Ramsey panel reported that their analysis found that the probability that the 144.9 impulse pattern was not gunfire from the knoll was 22.3% (P=0.223), which means their analysis found that the probability that the impulse pattern was caused by gunfire from the knoll was 77.7%, another fact that is always ignored by critics who cite the panel's findings.

Moreover, former USDA research scientist Dr. Donald Thomas has proved that the NRC/NAS/Ramsey panel committed crucial errors in reaching their P=0.223 calculation, and that the probability that the 144.9 impulse pattern was caused by grassy knoll gunfire is virtually 100% (https://www.maryferrell.org/pages/Essay_-_Acoustics_Overview_and_History_-_part_2.html).

Dr. G. Paul Chambers, a physicist who has worked with NASA, with the Naval Surface Warfare Center, and with the Naval Research Laboratory, is unconvinced by the NRC/NAS/Ramsey panel's attacks on the acoustical evidence:

The National Research Council admitted that its calculations of the relevant
probabilities may have been “unduly conservative.” In fact, the report uses the
word “conservative” with regard to the statistical analysis a number of times. It
then goes on to state: “Except for the rather conservative analysis above, the
data do tend to cast doubt on the hypothesis of random impulse locations.” In
other words, the sounds on the tape do not appear to be caused by standard
random noises, like cars backfiring in Dealey Plaza. This seems to me a lot like
an admission that the Bolt, Beranek, & Newman impulse sequences were indeed
nonrandom data, and therefore attributable to something significant. As gunshots
were the only reasonable source that matched the acoustic signatures, it would
appear that the NRC doubted its own conclusions.

With regard to the crosstalk synchronization, the NRC report states, in an
appendix discussing this analysis, that:

“The analyses in Appendices B-1 and B-2 [of the crosstalk] may be subject to
some criticism. A certain amount of subjectivity derives from the fact that the first
observer was looking at the sound spectrograms from both channels while he
marked points on Channel 1. . . . However, this experiment was supplemented by
several variations that derived similar results. Some of these were more careful
to avoid the subjectivity and to reduce considerably the dependence aspects of
the experiment presented here. These are not reported in detail, because they
were carried out using xerographic copies of photographs using several scales,
and relatively crude measuring instruments (graph paper in place of rulers).”

This is an admission that the first technique used to confirm the crosstalk
between the channels and to determine that the impulses of interest were not
concurrent with the assassination was highly subjective and therefore subject to
doubt. Moreover, the method they used to confirm the first technique was so low-
tech that they didn’t even want to describe it.

I could speculate that they employed the zoom function on the photocopier;
however, precisely how they did this analysis was deliberately left vague and so
there is no hope of reproducing their work. In science, if other scientists are
to take conclusions seriously, it is essential to describe the methodology of what
was done to reach them in detail. Otherwise, the work doesn’t have validity,
because no one will be able to reproduce the results.

Dr. Barger himself responded to the issue of the crosstalk synchronization in a
letter to G. Robert Blakey in 1983, after the release of the NRC report, concluding
that the NRC synchronization was doubtful and that the original BBN conclusions
remained valid. (Chambers, Head Shot, pp. 106-107)

Dr. Chambers discusses some the impressive aspects of the acoustical evidence:

Weiss and Aschkenasy reviewed Barger’s analysis and conclusions. They found
that Barger’s analysis was valid and his conclusions supported by the evidence
on the tape. They concurred with his recommendation to conduct live-fire tests in
Dealey Plaza to determine the origin and direction of the gunshots, and they
approved his plan for acoustical reconstruction. . . .

In Dealey Plaza, the sounds of gunshots would produce similar echoes. When
recorded and captured on a specialized electronic device like an oscilloscope
that converts sound patterns into pictures, these echoes appear as “acoustical
waveforms” and appear as unique signatures of sound-producing events.

In the case of a rifle shot in Dealey Plaza, the acoustical signatures would differ
based on the origin, direction, and velocity of the shot, as well as the location
of the recording microphone. The echo patterns would depend on the timing of
sound reflections off building or other structures and obstructions in the plaza. . . .
A recording was made of the sounds received at each microphone during each
test shot, making a total of 432 recordings of impulse sequences. . . . Each
recorded impulse sequence was then compared with each of the six impulse
patterns on the channel 1 Dictabelt recording to see the degree to which
significant points in each impulse pattern matched. . . .

The time of the arrival of the impulses, or echoes, in each sequence of impulses
was the characteristic being compared, not the shape, amplitude, or any other
characteristic of the impulses or sequences. . . .

When the BBN team performed their analysis of the acoustical waveforms, they
found something extraordinary. When they compared the impulse sequences
from the acoustical reconstruction to the sequences on the original Dictabelt
recording, they found a number of significant matches. When the locations of the
microphones that recorded matches in the reconstruction were plotted on a
graph of time versus distance, it was found that the location of the microphones
that recorded matches were clustered around a line on the graph that was
consistent with the known speed of the motorcade. . . .

Of the thirty-six microphones placed along the motorcade route, the one that
recorded the sequence of impulses that matched the third impulse on the 1963
dispatch tape [the dictabelt tape] was farther along the route than the one that
recorded the impulses that matched the second impulse on the dispatch tape.
The locations of the microphones were consistent with the distance a motorcycle
traveling at about 11 mph would cover in the elapsed time between impulses on
the dispatch tape. . . . Applying a statistical formula, Barger estimated that since
the microphones clustered around a line representing the speed of the
motorcade, there was a 99 percent probability that the Dallas police dispatch
tape did, in fact, contain impulses transmitted by a microphone in the motorcade
in Dealey Plaza during the assassination. . . .

Weiss and Aschkenasy, specialists in sonar applications . . . examined Dealey
Plaza carefully to determine which structures were most likely to have caused the
echoes recorded by the microphone in the acoustical reconstruction that had
exhibited a match to the shot from the grassy knoll. They verified and refined
their identifications of echo-producing structures by examining the results of the
1978 reconstruction [the test firing in Dealey Plaza]. This approach allowed them
to look for matches in the data with a 1 ms [millisecond] correlation. . . . Matches
at this level of temporal precision substantially reduced the possibility that a
match could occur as a result of random noise.

In Dealey Plaza, echoes from gunshot test patterns arrive in two discrete
[different] clusters, differing in time by about 190 ms. Echoes originating from
structures along Elm Street arrive within 85 ms, while echoes from structures
farther back on Houston Street arrive in the last 95 ms of a typical 370-ms-
duration test pattern. I

n addition, a “muzzle blast” is usually prominent at the beginning of a gunshot
acoustical pattern, while an N-wave (a shock wave traveling faster than the
speed of sound due to the rifle bullet exceeding the sound barrier) arrives prior
to the muzzle blast. The waveform identified as the grassy knoll shot is shown
in figure 13. The presence of an N-wave in this waveform was consistent with
the acoustical signature of a supersonic rifle bullet. (Head Shot, pp. 96-102)

    Those around him and the World Wide Fake Newser's were just EXPOSED for FAKING that President Biden was "non compos mentis" for much of his 4 yr term. "Not of sound mind" to the point that the auto pen was being used extensively. Biden was filmed shaking hands with ghosts, wandering around the stage, and falling off of bicycles. They did Everything they could to cover this up. Yet, you scoff at possible "faked evidence" in the assassination of JFK? Seriously? Look around you.

And everybody is writing about how in Russia, people just fall from the windows of building and that is because of Putin and which is FAKE NEWS and propaganda, because Putin really dont have kill anyone, becuase there are no people´s election in Russia, but these assassinations are only in these democratic states and why these politicians must be killed, if the people elect good politician that dont please with rest of the top elite.

United States democracy which is like a NAZI dictatorship where the leading elite kills all honest politicians

You believe that dictators don't assassinate their opponents because they don't have to worry about elections? They aren't worried about their political opponents because they rule in one party states and any threats to their power can be dismissed? So Stalin or Mao didn't have their opponents killed? All of those accounts - the Great Purge - are false?

And Putin doesn't kill his opponents because he doesn't have to worry about elections? (Russia has elections but they are greatly rigged). So what happened to this guy? He's Alexander Litvinenko? He wasn't assassinated?

[Steve M. Galbraith]

Yes, folks, "they" successfully covered up their murder of JFK just like the Biden people successfully covered up his senility. Nobody saw through it.

We were all fooled about Mr. Biden's mental acuity. He came across as sharp and on top of matters but in reality he was non compos mentis.

And just like they covered up for Biden, all of these Republicans and Democrats and the news media and three generations of Americans have covered up for the assassination of JFK. It's all very logical.

Of course "all the evidence is faked" maven Michael T. Griffith believes the long-debunked Dictabelt evidence!

But he doesn't believe the scenario of the shooting that the Dictabelt analysis theorized. The recordings reportedly show four shots from two locations. Three from the TSBD and a fourth shot from behind the fence.

Two locations. Two shooters.

But he believes there was triangulated gunfire, shooting from three (at least) locations. He believes there was a shooter on top of the linen truck. And "possibly" Babushka Lady firing a camera gun.

If the Dictabelt evidence and analysis of the shooting is true then there were two shooters. No triangulation, no shooter from the linen truck, no Babushka Lady.

But his response, of course, is that the other shooters used silencers or suppressors. Or something. It's always something in conspiracy world, another conspiracy somewhere to explain the first conspiracy. It's conspiracies all of the way down. So he'll both agree with the Dictabelt and reject it.

The perfect example of conspiracy mindset. Evidence says both "A" and "not A", it's both legitimate and illegitimate, real and corrupt. The *same* evidence.
