MAJOR TIP -- Butler Trump Rally Ballistics: Rifle Sounds: Look at the Naturally-occurring Correlative Signatures Suggesting Different Weapons or Firing Locations

A different temporal structure of naturally-correlated slow waves characterizes the first three, versus the following cluster of five, bullets---spectral analysis of frequencies is insufficient.

UPDATE 2024-10-21, VIDEO: Testimony by snipers; suspected gunfire from trees, not AGR Building. Review, consider and evaluate. https://x.com/I_Am_JohnCullen/status/1848409052633559512/video/1

Yesterday, I saw a video where a gentleman provided an expanded view of the three plus five-clustered shots attributed to Thomas Crooks in the corporate press. Unfortunately, I am now so far unable to find his video. (If you can help me locate this video, I would like to provide proper citation.)

The presenter cleverly expanded the time scale and synchronized the starting points of the total of eight shots: the three initial shots followed by five shots in a more rapid-fire pattern. The eights shells on the roof of AGR Building 6—poorly (according to standards of crime-scene methodology) and belatedly presented to us by the law enforcement officials—are offered as probative evidence that Thomas Crooks fired all of the eight shots, three then five.

In the above-mentioned video by a citizen journalist/forensic analyst, the presenter employed the frequency spectrum analyzer to no avail, at least accourding to what was presented to the viewer. I will return to this point later.

I have considerable experience as a electrophysiologist analyzing compound action potentials recorded from the nervous system—that is—bursts of electrical “spikes” traveling along each nerve cell, bundled into a nerve comprising many such cells, and combining their reports to make a noisy cacophany. From these “chattering” nerve cells—like the combined sound of a mass of theater goers in a lobby during intermission—it is difficult to discern the many disparate messages. But as with the separate conversants in the lobby of the theater, the muscles and glands which the transmitting nerves target can make meaningful “sense” of the incoming signals n terms of coordinated action. In order to disclose deeper causes and otherwise hidden patterns, electrophysiologists frequently employ autocorrelative (between identical or similar signals [added later 08-05: “or better said, autocorrelation techiques compare the same signal with itself by repeatedly shifting the signal by a small amount and adding the signals together in order to find its internal, repeating, dominant frequencies—we’ll leave it at that for now]) and correlative methods (between signals of different origins, targets or times). By happenstance, along with the video maker, I was able to detect patterns in the recording of gun shots from the Butler Trump Rally that deserve more investigation. The correlation of the distinguishing slow-wave patterns in the three- and five-shot clusters made a a bit more mechanistic sense to me, or at least I am able to supply a bit more terminology to the phenomena and maybe recognize a tiny bit more of their potential significance.

In both groups of shots during the putative, attempted assassination of former President and now-candidate Trump (that is, again, the three shot- and the five shot- group) there are singular coincidences of slow-wave overlaps to the exclusion of the surrounding, noisy, high frequency waves occurring before and after. This slow-wave pattern is temporally coincident among all three of the initial shots and—separately—among the five-shot group. Put another way, the slow wave patterns occur at—and are locked to—consistent times after the beginning of the bursts.

It must be pointed out that it is not clear that the producer of the video attempted to make the time scales between the three-shot group, and that of the five-shot group, match precisely. It appears instead that this presenter aimed to match a subjective judgement of the ends of the burst match between the three- and the five-shot patterns. It is likely that this effected something close to equidistant time scales between the two patterns, but in subsequent analyses this detail should be paid attention to and tidied up.

What is very important to note is that the temporal occurrences of these slow-wave patterns between the three- and the five-shot patterns occur at different absolute times relative to the beginnings of the shot patterns. More specifically, I recall the slow-wave pattern occurring later in the five-shot pattern than in the three-shot pattern.

This phenomenon of the timing of the characteristic slow-wave pattern of coincident und-pressure waves points to differences in the weapons (and types of weapons) of origin, the acoustical and distance properties of the surrounding environment or structural situations, or some or all of these factors. This strongly suggests the possibility—if not probability—that there were two weapons fired and fired from different locations, distances, environments, acoustic situations or gunmen. For instance, firing a similar weapon from inside a building would undoubtedly produce such different signatures.

As a final, small but critical, note regarding the video presenter’s unprofitable examination using spectral analysis of frequencies through whole bursts, this technique combines all frequencies that can be found within the period of the burst. This is, indeed, an important property to investigate as a preliminary step. It is not completely surprising that this did not produce a salient difference between the three- and the five-shot clusters of shots. The autocorrelation of the component waves (from which a frequency spectrum is derived) within a burst ignores the structure of the waves relative to absolute time. The correlation of the waves at a point in absolute time relative to the beginning of the burst is a separate informative characteristic, and the video maker is to be complemented for having recognized that some significance can be derived.

I am only speculating for the purpose of clarifying what is being entertained, but one might imagine that the correlated, prominent slow waves may represent the passage of the bullet just past the opening of the muzzle where there is a momentary, relative occulsion of the opening in the production of air-pressure waves produced either by compaction of air when the bullet is proceeding down the barrel or by the explosive expansion of gases as the bullet is freely beyond the barrel opening. At this point, with bullet partially in and partially outside of the muzzle, the compression wave might be imagined to be solely due to the mass of the bullet displacing the surrounding air and producing a slow wave. To emphasize, however, I will completely and happily defer to a ballistics engineer to comment or correct this very hypothetical model made by a complete outsider.

In addition, the muffling or sound suppression that results from firing from in a building or confined space and through a window or, for example, a drilled hole (recall if you will, the D.C.-sniper case of 2002 involving John Lee Malvo and John Allen Muhammad).
