If a CT could come to accept the "SBT," would he or she remain a CT?

MG--    "If Knott Lab's study had confirmed the SBT"

Then Knotts Lab would not have made such fools of themselves. I thought you stated how competent they were. What happened that they came up with the useless crap that they did?

You guys are like Flat Earthers after being shown satellite photos of the Earth. Knott Lab is one of the most prestigious, recognized forensic engineering and digital reconstruction firms in the country. They've worked on numerous high-profile cases. That's why they were chosen to do the SBT trajectory analysis.

But, oh boy, when the news came out that Knott had debunked the SBT, you guys not only rejected and misrepresented their detailed analysis but started smearing them as incompetent, sloppy, etc., etc.

And, again, Dr. Robert Piziali, who supervised the Failure Analysis trajectory study, admitted under cross-examination that JFK's Z225 reaction proves he must have been by no later than Z221. That admission alone blows to pieces the silly Z224-lapel-flip SBT.

BTW, Dr. John Lattimer, another devout WC apologist, also admitted that JFK's Z225 reactions proves he must have been hit by no later than Z221. If memory serves, Lattimer said Z220 was the moment of the hit.

You guys can't even accept facts when they come from your own experts.

And, FYI, Knott Lab, after creating the first exact digital replica of Dealey Plaza from a laser scan of the plaza, enabling them to measure point to point anywhere in the plaza, matched images from the scene and the Zapruder film using photogrammetry. With a photogrammetric process known as match moving, using every available film and photo of the shooting, they synced key Zapruder frames into the digital replica of the plaza, something that had never been done before. The match moving enabled Knott's experts to identify the correct locations of Kennedy and Connally in the vehicle and, crucially, in relation to the TSBD's sixth-floor window, and to establish their positions frame by frame throughout the shooting.

You can’t form an opinion by watching the films yourself? It takes someone to tell you what to think?
Knotts Lab could have produced something worth acknowledging but instead failed to ask themselves the simple question—does this make sense and made fools of themselves.

You still can't explain the obvious problems with their cartoon?

[Jack Nessan]

It is what I thought. All smoke and no fire. Knotts Lab is nothing but a joke. All the experts doing your thinking for you and that has left you unable to explain the obvious errors in Knotts Lab’s dubious work. If you cannot explain the problems with the animation, is there any way you can ask the experts to help you?

A "cartoon"? You mean the computer-generated animation based on the laser-scanned digital replica of Dealey Plaza, based on every known photo and film of the shooting, and based on a photogrammetric match-moving analysis that enabled Knott's experts to identify the correct locations of Kennedy and Connally in the vehicle and in relation to the sixth-floor window frame by frame during the shooting?

You guys gushed over Dale Myers' "cartoon" (read: animation) that pretended to show the SBT was possible. You didn't dismiss it as a "cartoon."

I notice you said nothing about the fact that Dr. Piziali, who oversaw the Failure Analysis test, admitted that JFK's Z225 reaction proves he must have been hit at least four frames earlier, which destroys the silly lapel-flip SBT. Just never mind when your own experts refute your myths, right?

Obviously, you're never going to admit you're wrong about the SBT, because then you'd have to admit that more than one gunman fired at JFK.

Where can one read the Knott study? Not a synopsis of the study or a video synopsis of it, but the actual full study itself. What generation copy, or copies, of the Zapruder film did they use? Did they use the Betzner and Willis photos? If so, what generation copies were they? How far inboard of JFK did they determine Connally to be? Did they factor in the right rotation of Connally when concluding that the SBT could not work? It seems that they did not. In a video synopsis of theirs, they say that they found a significant angle difference between the entry/exit points on JFK and Connally.

MG: The only forensic engineering and digital reconstruction firm that has analyzed the SBT trajectories, the prestigious Knott Laboratory ...The Knott SBT trajectory analysis dwarfs all previous analyses in sophistication and data volume

Not true. Failure Analysis Associates was (and still is, under the name Exponent) performed a trajectory study in 1994 for the ABA mock trial. It was scientifically superior to the amateurish, half-finished mess that KL did. At the very least, FaAA understood that they needed to account for uncertainties in the exact position of the bodies and the locations of the wounds. The only way that the KL study surpassed the others is in the sheer volume of data. But that's because of the tool they used to get topographic data; the great majority of the data generated is useless to this particular task.

I'm not familiar with the particulars of the FAA study done for the SBT trajectory. However, I suspect that it does not reach the gold standard of the study done by the ITEK Corp in 1976. The ITEK film analysis placed Connally's face 6.4" +/- 2.2" inboard of Kennedy. They had the original Zapruder film at their disposal, as well as a first generation copy. They also had high quality copies of the Betzner and Willis photos. Among their team were those with experience in photographic science, special photographic processing, photo interpretation, image analysis, coherent optical image processing, photogrammetry, and digital image processing. When factoring in the approximate 30 degrees right rotation of Connally, the SBT lateral angle of trajectory fits well beyond the reach of those trying to destroy the SBT.

Knott does not state how far inboard that they determined that Connally was. Nor are they specific on what materials they used for their study. They only say that he was not 6" to 10" inboard and that they used 25 historic photographs and 7 frames of the Zapruder film. What copy of the film they used is not revealed by them. Nor are we told what the historic photographs are. They have not made their full study available. All we have is worthless claims that lack any real support.

This is laughable nonsense. If Knott Lab's study had confirmed the SBT, we both know you'd be singing a very different tune.

BTW, Dr. Robert Piziali, who oversaw the Failure Analysis study, admitted under cross-examination that JFK's Z225 reaction proves he could not have been hit later than Z221.   

This is just so much nonsense. FYI, the amount of data is crucial in any trajectory analysis. The Knott Lab study was far more sophisticated than the Failure Analysis study on several counts, starting with the fact that Knott did a laser survey of Dealey Plaza and constructed an exact digital replica of the plaza. That's kind of, sort of, important for any trajectory analysis of the SBT, don't you think? The technology to create that replica didn't even exist in 1994.

Knott Lab focused on the key, crucial issue of JFK's and Connally's positions. They were aware of the questions about the location of JFK's back wound, but they proved that no matter which location you choose, JFK and JBC were not aligned with a trajectory that traces from Connally's chest exit wound through his back wound and back through JFK's throat wound and back to the sixth-floor window. It just doesn't work.

Folks, the smears and disinformation coming from Todd and WC apologists about the Knott Lab SBT study is really misleading and unserious.

MG: If Knott Lab's study had confirmed the SBT, we both know you'd be singing a very different tune.

Now you presume to read my mind! But, sorry, no. You are simply wrong. Had it supported the SBT, I would put it in the same place that I do with Myers' similar effort: interesting, but nowhere rigorous enough for the conclusion to be significant.


MG: FYI, the amount of data is crucial in any trajectory analysis.

That's not true at all. All you need to know is the relative position and orientation of the gun and targets, as well as the location of the bullet holes in the targets. Anything beyond that might make for a prettier presentation, but it's superfluous to the actual analysis.

The advantage of using a 3d laser scanner over older methods, like laser theodolites, is that it's faster and cheaper. Not necessarily better or more accurate. With the 3d scanner, a couple of guys can survey something like Dealey Plaza in a couple of hours. Older methods would have required a days and at least one full survey team to do the same thing. The other advantage is that the laser scanner will interface directly to your CAD/visualization software so the data generated by the survey can be directly transferred and automatically transformed into a 3d model. You probably get a more accurate model, but realistically any improvement is miniscule when cast against the scale of the problem. Going from +/- 1" to +/- 1/8" is an improvement; however, at 65 yards, the 1" max difference results in a 0.24 degree difference in angle. That's not even a rounding error in this context. 


MG: Knott Lab focused on the key, crucial issue of JFK's and Connally's positions.

So, wait. First you make this big fuss about KL using the laser scanner to survey Dealey Plaza. Then you forget that and switch to "oh, but they were really focusing on the positions of JFK and JBC," a subject for which the laser scanner is useless, unless you have a time machine.


MG: They were aware of the questions about the location of JFK's back wound, but they proved that no matter which location you choose, JFK and JBC were not aligned with a trajectory that traces from Connally's chest exit wound through his back wound and back through JFK's throat wound and back to the sixth-floor window. It just doesn't work.

They also have Connally leaning forward, which he wasn't. JFK is leaning backwards, but it you look at the other photographs take of the limousine that day, he's always leaning forwards when he turns to the left. Connally is also slightly larger, especially through the shoulders. They put the back wound at the JFK's centerline, which is indefensible, and also artificially pushes the trajectory to the left. They have the rifle being fired from the west side of the SN window, like they don't really know where the sniper's nest actually was. A close look at the materials released by Knott Labs, and it looks, at best, like a half-finished project that was cut short, or maybe something based on faulty research. It looks nice at first glance, but fails to convince on thorough examination.   


MG: Folks, the smears and disinformation coming from Todd and WC apologists about the Knott Lab SBT study is really misleading and unserious.

Ad hominem well-poisoning isn't a convincing substitute for evidence and logic. Maybe you should try the latter?
