  1. I think it's all about how much of this evidence can be put into the "certain" category as opposed to the "possible" or "probable" categories. It is quite noticeable how many witnesses reported smelling gunpowder, including those in the motorcade such as BJ Martin, Dearie Cabell, and Ralph Yarborough. Curiously Earle V. Brown was over 100 yards away from Dealey Plaza towards the Stemmons Freeway, and he also reported the smell. This very wide range of people in different locations does make me wonder whether whether it was actually the smell of smoke or gunpowder, or whether it was just a psychological reaction to the sound of gunfire mixed with real ambient smells (e.g. vehicle exhausts). With the lack of independent or objective proof either way it's hard to be certain, so I would put the smell of gunsmoke into the "possible" category. In terms of the reports of visible smoke in the knoll area it's slightly different as it's much more specific. Several people refer to it in the same location so I do feel there was something in the air floating around, but was it related to a gun? Unless someone was using a musket or a cannon I suspect not. The "smoke" may have been related to the explosion we see in the Zapruder film at Z313, with vapour and debris in the air, or possibly vehicle exhaust fumes drifting towards the knoll as they all roared away (the wind was blowing that day so airborne particles would have moved around). It's hard to be certain of the exact cause, but yes, I'm sure something real did indeed stimulate so many identical witness reports so I say this is "certain", but the actual cause of the airborne material is somewhat moot.
  2. As far as I know Calvery was never interviewed and never gave any more details. It's a great pity as she could well have given more info regarding the bushes she was referring to. I agree, the major failure was the lack of a proper investigation immediately following the events as that would have conclusively proven whether Oswald acted alone or had assistance. Along with the awful autopsy I don't see how anyone can now prove with certainty what really happened as the full truth of the crime scene was never properly established in 1963. Without that information, all theories will struggle to be promoted to "fact", including the lone nut theory.
  3. I think this woman was Gloria Calvery. She was described by JM Smith as "in hysterics", and mentioned specifically by Billy Lovelady: Mr. LOVELADY. I thought it was firecrackers or somebody celebrating the arrival of the President. It didn’t occur to me at first what had happened until this Gloria came running up to us and told us the President had been shot. Mr. BALL. Who was this girl? Mr. LOVELADY. Gloria Calvary. 6H338 - https://www.history-matters.com/archive/jfk/wc/wcvols/wh6/pdf/WH6_Lovelady.pdf This was corroborated by Bill Shelley who said she was crying which matches the "hysterics" description: Mr. SHELLEY. Gloria Calvary from South-Western Publishing Co. ran back up there crying and said “The President has been shot” and Billy Lovelady and myself took off across the street to that little, old island and we stopped there for a minute. 6H329 - https://www.history-matters.com/archive/jfk/wc/wcvols/wh6/pdf/WH6_Shelley.pdf This brief meeting of these few witnesses is featured in my animation and the timings seem to neatly tie everything together on the Elm Street extension where JM Smith, Lovelady, and Bill Shelley seemed to go when they were all seen in the Couch film within 30 seconds of the last shot being fired. This is a very troubling account, and with Weitzman also mentioning Secret Service people this is very odd. The only Secret Service agent I know of in Dealey Plaza was Forrest Sorrels but he went to the hospital first. He didn't return the Dealey Plaza until about 20 minutes after the shots were fired: Mr. STERN. Just a minute. How much time do you think elapsed from the time the shots were fired until the time you returned to the Book Depository? Mr. SORRELS. I don’t believe it could have been over about 20 minutes, because we went to the hospital just as fast as we possibly could, and I wasn’t there very long. And we came back as fast as we could. Of course we didn’t get back as fast as we went out there, because traffic was moving. 7H347 - https://www.history-matters.com/archive/jfk/wc/wcvols/wh7/pdf/WH7_Sorrels.pdf
  4. Yes indeed, I take all evidence at face value until it can be proven wrong, and in the meantime I simply point out any conflicts, discrepancies, or ambiguities I have found. I have published a complete list of over 400 witnesses with analysis, and referenced every film and photo in the public domain, so it's not fair to say I have ignored anything. I have been saying for over two years that the current "lone nut theory" with a missed shot at Z160 or before belongs in the garbage can, so to suggest I support the official story is wrong. I don't rule out a three shot scenario involving Lee Harvey Oswald, but the missed shot must have been fired well after the head shot as many witnesses reported this back in 1963. I'm also happy to consider other evidence based theories about the crime scene, so for example I think it's quite possible that two shots were fired in rapid succession during the shooting (thus requiring a second gunman). I accept that by disagreeing with 99% of theories on both sides of the debate I will never be popular, but as I've always said, I do my work without fear or favour (including me correcting my own mistakes when people present evidence or analysis, such as in this very thread).
  5. The timing of the first shot does seem clear thanks to the witnesses, especially those with cameras. Hugh Betzner said he heard the first shot just after he took his photo at Z186. The Zapruder film start shaking and blurring around Z190-Z210. Phil Willis said he heard the shot just before he took his photo at Z202. The other witnesses standing nearby at the intersection, or in the motorcade seem to agree with the timing with no witness unambiguously claiming an earlier shot.
  6. Sure, which merely demonstrates that she was at the interesection when the first shot was fired which I agree with. She never claimed the car stopped at that point though, and the claim of the Mayor's car stopping at that point is your own interpretation. No witness mentions it, and no film or photo shows it. In fact, the Wiegman film directly refutes it as the car is cruising through the intersection at 8-10 MPH just a few seconds after the first shot: Which film, photo, or witness suggests that the car was stopped by the police at the intersection?
  7. Indeed, Cabell's statement matches the animation rather nicely at roughly the time the car stops (Z420-Z450). She mentions seeing the child being thrown to the ground which must have been the Newman family (whose turn is briefly in the Nix film after Z313), and the green dress lady is probably Beatrice Hester. At Z420-Z450 Cabell has a perfect view of both events unfolding: If she was back at the intersection she would have struggled to see all this as her view would have been distracted by the crowd nearby. Here are some Wiegman composites showing the scene including Mr Newman pushing his child to the ground, and the dispersing crowd so Cabell could see Hester falling near the pergola when the car had just stopped:
  8. The Mayor's car didn't stop at the intersection, it stopped well into Elm Street. The Wiegman film shows the Mayors car cruising around the turn and then stopping a few seconds later. The only cars that stopped on the intersection were the camera cars as shown by the Couch and Darnell films. Dearie Cabell referred to the first shot being fired while she was turning on the intersection. Ergo the next two were fired while she was on Elm Street. No films, photos, or witness statements support the notion of the Mayor's car stopping at the intersection.
  9. That is indeed the Presidential limo in the Wiegman frame and is used to triangulate and connect that Wiegman frame to Z447 in the Zapruder film. Sadly there was no film of the Mayor's car stop but we know it happened near Z447 as we see the national press pool car behind it with it's brake lights on indicating that the Mayor's car had stopped or was stopping. We next see the national press pool car in the Bell film (the top image here has it's distinctive rear end on the left hand edge between the sprocket holes): Then the Bell film pans to see Charles Hester duck into the pergola shelter which matches the end of the Wiegman film segment (26 seconds in total, or 15 seconds after Z447, if Wiegman was recording at 24 FPS, or a second or two less if it was 29 FPS). We can deduce therefore than the cars stopped very briefly for a few seconds, and no more, as the cars had both passed the grassy knoll steps well before the Wiegman film ended. The Mayor's car stops for about 4 seconds in the animation, which dovetails perfectly with all of the other action recorded by the films at the time, and even some things that weren't recorded such as Hargis running across the road towards the lamppost. As far as I know there are no loose ends in the animation, and the film evidence matches perfectly with the larger body of witness evidence. Yes, there are the occasional disagreements between witnesses, but overall the continuity of events can be worked out with no sinister loose ends remaining. Dearie Cabell said she was passing the TSBD when the first shot was fired, which fits the animation perfectly if the first shot was fired Z180-Z220. The Zapruder film shows the Mayor's car behind the spectators behind the reflecting pool at exactly Z180 so this part of the sequence is very accurately known. The Wiegman film and the Dorman film prove that the Mayors car didn't stop until it was well down Elm Street and well past the traffic lights as shown in the Z447 Wiegman frame earlier in this thread. The films match each other, and they match Dearie Cabell's testimony. Many parts of this case are unclear or untrustworthy, but this part of the Dealey Plaza sequence is crystal clear and highly reliable thanks to the films and the witnesses.
  10. Here is the map of witnesses reporting one or two shots well after the head shot: Compared to the previous maps, far fewer witnesses are certain they heard shots during this timeframe, although enough are adamant that shots were fired around Z360-Z400 to accept this as corroborated. A few seemed to hear a pair of shots, such as Mary Moorman and Jean Hill who gave very clear interviews on the day explaining that sequence of events. The dataset is too small to spot any clear patterns, although once again Elm Street is the main area of these witnesses. One thing that is very noticeable here is how no witnesses in the Presidential limo, SS follow up car, or VP car actually heard this shot or shots. My view is that this is due to a couple of reasons: A very loud siren was being emitted from the Secret Service follow up car which distracted enough people who were in the immediate vicinity (judging from the map nobody within 30 feet of the siren heard the shot(s)). The stressful nature of events startled many people, especially those who witnessed the head shot which distracted them from the final shot(s) (many bystanders literally turned and ran just after Z313, underlining the horrific nature of the events they had just witnessed). By contrast, those witnesses further away from the siren who weren't terrorised were able to report the final shot(s) in the sequence. The best example of this were those in Camera Car #3 who all reported that the final shot was fired as they began their turn onto Elm Street, so they must have been very close to the TSBD gun and well away from the siren or the chaos unfolding on Elm Street. In particular Malcolm Couch gave enough detail in his statements to identify where the car was located when he heard the first shot fired around Z190-Z220; the second shot near Z313; and the final shot around Z360-Z400. Thanks to the Hughes film and the Zapruder film we have a very accurate measure of where the camera cars were at those times which makes it fairly easy to convert the witness statements to a timeline of when the shots were fired. Studying the raw data from over 400+ witnesses is a little daunting and rather hard to digest in tabular form, so many thanks to Eddy for suggesting the idea of looking for patterns on the map regarding the double bangs and witness locations as I think it makes it easier to understand the very complex crime scene.
  11. In the Wiegman frame, the hard top car just about to pass Hargis is the VP SS follow up car. The continuity and synchronization of this works perfectly in the animation. The animation frame you quoted was from Z368, but the Wiegman frame was over 4 seconds later at Z447 which is why the cars had all moved down Elm Street a little bit more. The Mayor's car didn't stop for more than a few seconds, but the longer delay came thanks to the camera cars which were very sluggish to get away as several cameramen got out of the cars and took films and photos before returning to their cars. The Wiegman frame is a little blurry due to Wiegman running fast down Elm Street so I wouldn't worry too much about some of the odd visual artefacts and lack of sharp detail.
  12. Here is the map of witnesses reporting one or two shots in the vicinity of Z313: Compared to the first shot(s) circa Z225, there are far more witnesses who heard double bangs. Just like with the first map, the main group of witnesses who heard this double bang were situated on Elm Street or the bridge over Elm Street (almost a straight line from the TSBD or Dal-Tex buildings to the bridge I would say). A handful in the Houston and Main Street area heard a double bang, but not many. The final piece of this work will be the much smaller group of people who heard a shot or shots well after Z330, which I hope to complete by the end of the weekend.
  13. The general pattern of the vehicles would be the same: each of the cars would have decelerated into the turn, and then accelerated out of the turn at a certain point. However, the exact speed going in, out, and the point of acceleration would vary from car to car. The exact point you referenced for the Presidential limo and the camera car is indeed the same at about 8-9 MPH, but other cars like the VP car and it's SS follow up seem to be a little quicker at 9-10 MPH. It's not a big difference, and both seem reasonable guides for what the other cars must have done. With the Mayor's car being directly behind the VP SS follow up travelling at 9-10 MPH, that must also be a reasonable speed for the Mayor's car as the driver would have been looking very closely ahead as the car in front accelerated away. Sadly, with no other cameras recording this area at the same time we can't really be certain of the exact speed of the Mayor's car at all points on the bend. The only certainty is that we see where the Mayor's car is at Z180 in the Zapruder film, and also Z447 in the Wiegman film about 14.6 seconds later. In the animation the computer program decelerates the car at Z180, and starts accelerating it soon after such that we don't see it in the Altgens 6 photo at Z255, and it's then in the right place to be stopped at Z447. By slowing down the car during Z180-Z280, you will necessarily speed it up later in that sequence towards Z447 (unreasonably pushing it over 15 MPH), or it creates a timing gap in the Zapruder film.
  14. Eddy, I managed to map the witnesses reporting the first shot noises circa Z180-Z240 here: Of the 400+ witnesses I studied, about 100 of them can be pinned down to hearing a shot in this rough timeframe thanks to them mentioning JFK reacting or the positions of the cars. The witnesses who reported two shots around this time are in purple squares, with a single shot being yellow. There aren't many double bangs, but there is one main cluster, with the centre of this being the Presidential limo (as identified by the large ellipse). The other two minor areas are the bridge, and also the two cameramen Nix and Bronson on or near Main Street. The most obvious pattern here is that about 90% of witnesses heard a single shot at the beginning of the shooting which means 90% of the witnesses don't accept the modern lone nut theory which requires an extra missed shot at Z160 or before. Even in the 10% part, most say that the two shots were on top of each other with barely any time between them, which as far as I'm concerned consigns the very early missed shot theory to the trash can as it requires 3-5 seconds between those shots. Over the weekend I will do the timeframe around Z313, which has dozens of witnesses reporting a double bang.
  15. Yes, I had the Mayor's car moving slightly faster in that part of the bend than the Presidential limo. This is partly due to the speed constraints later due to the Mayor's car probably being at a standstill by Z447: This drags up the speed somewhat after the start of the Wiegman film, followed by a short braking operation as they saw the chaos unfolding ahead. In version 2.3 I have him peaking at about 13 MPH followed by him stopping at Z430. With no film depicting this timeline it's rather tricky to be certain, but stopping the Mayor's car at Z410, Z430, or Z450 would change the speed, as well as the tightening of the vehicle cornering you mentioned earlier (which seems quite reasonable, although difficult to know with certainty due to the lack of clear films of that area at that time). There is a trade off between speed and the line taken around the corner, as the tighter the turn the less distance is travelled, but also the slower the car must be travelling. The bikes had the same issue, with the inner bikes being near 5 MPH, and the outer ones being near 10 MPH.
  16. I think visually depicting the locations of witnesses who heard single and double bangs on a map of Dealey Plaza would be very interesting, just in case it revealed a pattern. When I get some free time I will look at doing something like this as I think it could be quite useful to know. About 100 of the 400+ witnesses gave enough information to know roughly when they heard the shots, so there should be enough data to spot a pattern if there is one.
  17. Do you mean that the animation map needs adjusting to shrink the corner down a little? This looks like the HSCA survey you are using, so it's worth mentioning there are some disagreements between this, the Warren Commission survey, and the other ones folks have put together over the years. Do you have any high resolution aerial photos from 1963 that might nail down the exact nature of the curve relative to the fixed landmarks? I have seen some later photos of that corner, but there have probably been changes since 1963. Here is CE699 which isn't the best resolution: https://www.history-matters.com/archive/jfk/wc/wcvols/wh17/pdf/WH17_CE_699.pdf
  18. I have indeed read things like the Thompson/Aguilar article here, referencing some interesting interviews with witnesses regarding the original bullet found on the stretcher: https://history-matters.com/essays/frameup/EvenMoreMagical/EvenMoreMagical.htm Looking at the issue of the first shot or two, I do find it very difficult to fully explain the events we see in the Zapruder film relative to the victim injuries, and CE399. The single bullet theory has a number of strengths, but it also has problems regarding the trajectory and why CE399 wasn't damaged more after breaking so many bones. Did employees of the FBI subvert the investigation? Of course, the HSCA proved this by getting James Hosty to confess to destroying Oswald's threatening note, presumably to avoid the negative attention that it would attract (i.e. why didn't the FBI do something about Oswald and his subversive threats before the President drove past his place of work?). Who knows where else this may have happened in this case to avoid embarrassment? In general I feel we are missing a piece or two of the jigsaw, probably due to the inadequate autopsy and the rather haphazard investigation. Two commonly discussed options I have heard on each side of the debate are: Lone nut argument: JFK had a curious slouch due to waving (and possibly his back problem), which explains the trajectory from his back to throat wounds coming from the sixth floor window. CE399 is authentic and wasn't damaged more due to being slowed down by going through JFK first before hitting bones in John Connally at a greatly reduced speed. Conspiracy argument: The flatter vertical trajectory through JFK is explained by the bullet coming from a lower source such as the Dal-Tex building (perhaps hinted at by the arrests there soon after the shooting, e.g. Jim Braden). CE399 is a red herring due to being fraudulently introduced when the authorities didn't want to acknowledge that a conspiracy occurred. Sadly both seem rather moot as it's impossible to prove either with any certainty, but I suspect the truth is close to one of these two options.
  19. This camera data is an interesting reference, thanks for sharing it. So it looks like the 36.5 seconds of footage Wiegman took was just about as much as he could get without winding the camera back up (37 seconds). This might explain why the last couple of items were so short, as he desperately tried to use up the remaining frames before the camera spring was completely unwound. I tend to agree with you that he would have done the whole sequence on a single wind as he probably didn't have time to crank it up again. Did you try speeding up the Wiegman film to account for the 29 FPS estimation based on the Mayor's car position? (adding an extra 20% of speed to your media player should do the trick) I find the film speed at 29 FPS to be more natural, such as the people at the end running and Charles Hester jumping up. At 24 FPS the speed feels a little sluggish and unnatural.
  20. Hi Benjamin, I hope you find the work useful. Having a complete real-time motorcade reconstruction based on all of the photos, films, and witness statements helps to explore the various theories regarding the crime scene. In some cases it exposes some of the mistakes that witnesses made in their statements such as timing, but in general most of the witnesses seem to be correct regarding what they saw and heard. Many of the contradictions between the witness statements can be resolved by understanding that some were distracted and missed the first or last shots. After accounting for that, I noticed things started to fit together a bit more. The exact timeline of Connally's wounding is tricky to judge due to the subjective nature of photo-analysis, but the first time I see him moving abnormally is about Z225-Z230 at the same time JFK raises his arms so I suspect they were both hit at roughly the same time. Have a look at a slowed down Zapruder film to see them both react at the same time, with Connally's hat moving upwards rapidly and his whole body seems to twist and flinch with discomfort: Whether this is a single bullet, or a pair of different shots I'm not sure, but the downward angle of 20-25 degrees through Connally does seem to match the sixth floor window perfectly if the wound occurred Z190-Z220 as the film would imply. The thing that baffles me is the flat trajectory through JFK, as this doesn't really fit Connally's wounds unless JFK was hunched forward somehow (which looks unlikely judging from the Zapruder film). As I recall, when Connally studied the Zapruder film frames before giving testimony to the Warren Commission he said he thought he was hit by frame Z230, so this might be worth considering. Connally's testimony is very interesting regarding the shots, as he insists that he wasn't hit by the first shot, but was hit about two seconds later. Here is a quote from his Warren Commission testimony which underlines this rapidity: "I knew it when I just looked down and I was covered with blood, and the thought immediately passed through my mind that there were either two or three people involved or more in this or someone was shooting with an automatic rifle. These were just thoughts that went through my mind because of the rapidity of these two, of the first shot plus the blow that I took," 4H133 - https://aarclibrary.org/publib/jfk/wc/wcvols/wh4/html/WC_Vol4_0071a.htm If this is correct then Connally is telling us that there was more than one gunman. Alternatively he may have been hit by the first shot, but suffered some kind of delayed reaction due to the shock from his injuries. Either way it's hard to match his statements with the popular modern lone nut theory which involves a missed shot fired at Z160 or before, followed by a 3-5 second delay before the single bullet hits the victims. Nellie Connally's statement also challenges the modern lone nut theory as she said the first shot hit JFK, and that the second shot came soon after, but before the head shot that we see at Z313. As we see from the Zapruder film, all of this happened in the five seconds during Z225-Z313, so three shots in five shots is impossible for the clunky bolt action gun found in the TSBD (not forgetting that many witnesses also heard another shot well after the head shot, which would be a fourth shot). I haven't studied the medical side too deeply, but from what I have heard from other researchers is that it might have been possible for the wrist wound to have occurred from the shrapnel which emerged from JFK's head and was projected forward in various directions. It's probably impossible to know with certainty, but maybe this explains why CE399 was not damaged more, i.e. it didn't actually hit the wrist bone and it simply went into the thigh directly from the chest wound? Judging from Z312 of the Zapruder film Connally's right hand was exposed and facing upwards at the time of the head shot so it's certainly possible for the wrist wound to have occurred then. I'm fairly open minded about exploring different theories to explain the crime scene evidence. Any theory that fits with the known facts and has no loose ends is well worth considering. A second gunman is quite possible, and judging from the witness survey I compiled, about 60% of those who gave clear information suggested that at least two of the shots were fired in rapid succession (within a second or two, which is impossible from the gun in the TSBD). The majority of these witnesses mentioned that this double bang was towards the end of the gunfire, although a few did hear a double bang at the beginning.
  21. That's right, in the earlier animation version I had a wider turn where the cars all sat in the middle of the centre lane, but I realised that most of the cars took the turn by being closer to the left hand white line at the beginning of Elm Street. In other words they cut the corner ever so slightly, rather than following a perfect circular arc. The exact position of the Mayor's car is tricky to judge as we don't see a white line for several seconds into the Wiegman film, so the best view is probably from the Dorman film here: It's not completely clear from this slightly blurry frame where the white line is, but a slightly earlier frames suggests it's just behind the car, but not hidden by very much (maybe the horizontal white area just behind the window frames?). There could be a slightly tighter radius if the car started turning slightly earlier on Houston Street, so anywhere near Z270 could work for the beginning of the Wiegman film. Z270 would mean a Wiegman film rate of about 27.3 FPS. Anyone can do this calculation as follows: Wiegman FPS = 264 / ((447 - START) / 18.3) 264 = Wiegman frames elapsed since frame 1 (to match Z447 with W265). 447 = Z-film frame sync point with Wiegman 265 (based on the Presidential limo location being visible in both film frames, triangulated with the lamppost). 18.3 = Average Z-Film FPS. START = Zapruder start frame synchronized to Wiegman frame 1. For example, using START=246 results in the 24.0 FPS that Dale Myers used.
  22. 33 Zapruder film frames (or close to two seconds) does seem to be the gap between my Wiegman film analysis and what Dale Myers concluded in his 2007-2010 Epipolar report here: https://www.jfkfiles.com/jfk/html/acoustics.htm For those reading this who don't know about what I call the "Wiegman Timing Anomaly", Myers said that the Wiegman film was recorded at 24 FPS (based on the assumption that 16mm film cameras typically used that rate in the 1960's). However, I have concluded that due to the measurements of the Mayor's car position I think it was closer to 29 FPS. Connecting the two second gap to the Towner film frame rate issues is an interesting coincidence that I hadn't noticed before. The other thing worth mentioning is that the Towner frame rate analysis is also locked into the Hughes film thanks to a 4.8 second segment which ended here: Chris, is there a similar problem with the Hughes film at 18 FPS, or are you saying the Hughes/Wiegman films are authentic and that the problem of a two second gap is just with the Towner film and the Zapruder film?
  23. Thanks for the tip, I'm glad my motorcade analysis could help in some small way! I should also express gratitude to the members of the forum who have helped me over the last two years to nail down the details and correct some of my mistakes along the way. Although I disagree with Josiah Thompson on the dictabelt issue, I'm very grateful to him for the amazing investigative work he has done in the case, and also the very cooperative attitude he has had towards other researchers. For example, he has taken time to share his knowledge on this very forum, which has been a great source of help for me for studying the witnesses and their statements. As an example of his public speaking, here is a video from 1975 where Thompson lucidly explains the various problems with the single bullet theory (10:50 to 23:40 in the video):
  24. Hi Stu. Apart from McLain, the other bikes in Dealey Plaza were in even worse positions to record the audio on the Houston/Elm Street turn: The presidential limo bikes were well down Elm Street so it couldn't be them. Officer Baker was on the wrong side of the road and was nowhere near the turn onto Elm Street, just like McLain (as proven by the Hughes film circa Z190). The other bikes were still on Main Street (Courson, Haygood, etc), or possibly just turning onto Houston Street when the shooting started. One or two three wheeled bikes were on Main Street, but they were nowhere near where they need to be on the Houston/Elm turn (as proven by the Hughes film showing Houston Street bereft of any bikes just before the Zapruder film started at Z133). The HSCA scenario, or the second animation which I mentioned in my previous post, is where I explored what Don Thomas and others think happened regarding McLain and Courson. Sadly I couldn't make the timing and continuity work unless McLain roared forward along Houston Street at 30 MPH from 10-15 MPH on the Main/Houston bend, so I think there is no chance that the stuck open mic on the bike was in Dealey Plaza. Last year someone suggested that the microphone that recorded the gunshot impulses onto the dictabelt could have been in Dealey Plaza but in the Mayors car or the Secret Service #2 follow up car (with the noisy bike with the stuck open mic being elsewhere in Dallas). I initially thought this might be possible as the animation shows those two cars are in roughly the right position on the corner turning onto Elm Street from Z175-Z313 during the shooting up to the head shot. For this to be correct then a police microphone would need to be in one of the cars and switched on, which I don't think we can know either way for certain. However, I then realised that in the seconds after the head shot at Z313, Sam Kinney in the Secret Service #1 follow up car started a very loud siren which many other witnesses reported (most notably Marilyn Sitzman who said it was the loudest thing she heard that day). As we all know by listening to the dictabelt recording, the only audible sirens appear 3-4 minutes after the alleged shots which means that whatever was recorded at the time of the assassination could not have come from any microphone in Dealey Plaza as the siren does not appear. Anyway, that's my current view, but as always I'm very open to re-evaluating things if anyone thinks I have made a mistake or there is a better explanation for the evidence.
  25. Well spotted Chris, I changed the start of the Wiegman film to Z280 as I found it smoothed out the deceleration of the Mayor's car as it turned onto Elm Street Z133-Z220 (and then the acceleration that followed a few seconds later on Elm after Z250). This slightly slows the film frame rate down to 29 FPS from the 31 FPS which I had before for the Z295 start of the Wiegman film, but it's still within the 27-31 FPS range which is my visual estimate of the true Wiegman film rate. If you think this causes any problems let me know the details and I will check these workings again.
