In contrast to conspiracy buffs, the "lone nutters" did experiments and proved, that the single bullet indeed was possible.

Only if you make a lot of assumptions about contradictory accounts of the wound locations, the exact positions of the limo occupants, and the location of the shooter.

But lots of things are possible.  Can they show that it actually happened?  And so what if it did?  How does that get you to the identity of the shooter?

The evidence are the 33 people (according to John McAdams) testifying that they heard shots from the grassy knoll. According to your interpretation of witness testimony this means, that there was a shooter at the grassy knoll!
No it doesn't.  The quality of a witness observation is depends on the ability of a human to make the observation.  Detecting gunshot sounds and the relative spacing is rather easy to do.  Determining where the shots came from is much more difficult. Direction is determined by the brain sensing a time difference between the sound wave front reaching each ear.  The sense of direction can be fooled by reflected sound. Dealey Plaza had many surfaces that reflected sound.  So I would expect that some people would be confused as to the direction of the sound source.  That confusion is reflected in the distribution of witness evidence. 

Having said that, many more witnesses said the sound source was around the TSBD. According the the analysis of earwitness accounts by DM Green for the HSCA (at 8 HSCA 140), the distribution of 178 witnesses was:

TSBD: 49  (27.5%)
GK:  21  (11.8%)
Other: 30  (16.9%)
Unknown: 78   (43.8%)

BTW, the book you quote actually supports my point of view on witness testimony, as it focusses on the fallability of such testimony. Quoting a part of the book and neglecting the rest is nothing else than quote mining!
Eyewitness identification evidence is problematic. Unless the witness recognized the person at the time of the event, eyewitness identification is really an opinion of a witness that the person being seen in a photograph or lineup is the same person that they saw earlier.

But, fact observation is fundamentally different.  As the studies referred to by Loftus show, where a detail is recalled by most eyewitnesses, accuracy is quite high - around 98%. This makes perfect sense. Where you have many witnesses independently saying the same thing, it boggles the mind to suggest that they all independently made up the same fact!

Any given witness can be wrong.  My point is that you do not have to know anything about and individual's reliability as a witness to determine that if 22+ people independently reported seeing a simple observable fact and 0 reported a different fact, you are making a big mistake if you find in favour of the fact that 0 people observed.

1. There are various photographs and x-rays, that can be used to find out the wound locations.

2. The position of the "limo occupants" can be established by photos and videos.

3. The location of the shooter can be established by aligning the entrance and exit wounds of JFk.

And how about you? Can you prove, that the single bullet didn't happen?

Quite easy, if you know the position of the shooter, you can search this place for further evidence and link it to the shooter.

No it doesn't.  The quality of a witness observation is depends on the ability of a human to make the observation.

But that contradicts your previous argument. Just to remind you, you stated:

An individual witness can be wrong. But if multiple independent witnesses report consistent observations, on what basis can that evidence be disregarded?

It seems, that you are trying to move the goalpost.

Obviously not, as many witnesses (including Tague!) testified, that they thought the first shot was a firecracker or  a backfire of one of the vehicles!

While this is surely true (see Zapruders testimony [I do not classify him as an "knoll witness" because of this fact]), can you prove this for every witness?

This is of course true, but it is no contradiction to a shooter at the grassy knoll! The common argument is, that a further shooter was present at the grassy knoll and this proves a conspiracy (which is actually not true).

What part of her book are you referring to? Is it table 3.1? If so, did you know, that this table represents the results of a multiple choice test? Now tell me, which investigator uses multiple choice tests for his interrogations?

I never claimed, that the witnesses made up this fact! You are just putting words in my mouth.You futhermore fell prey to the "argumentum ad populum fallacy". Just because a lot of people said, that something occured, doesn't necessarily mean, that something occured. You have to confirm this accounts by actual facts.

Well, to the best of my knowledge no witness ever observed, that a bullet fragmented, therefore it didn't happen (according to YOUR logic).

You would think so, wouldn't you?  Unfortunately, different panels examining the same materials couldn't even agree on where the entry wound in the head was located.

Somewhat.  Unless the areas of interest are not visible in the photos and videos.  And there's the problem of interpolating 3D position from a 2D image.

Quote
3. The location of the shooter can be established by aligning the entrance and exit wounds of JFk.

Assuming you can figure out where those are, IF they are entries or exits, and didn't deflect much in transit.  Then you can only get direction, not distance.  And there's even a margin of error on direction.

Quote

Did I miss your proof that it did happen?  I don't know if it happened or not.  Or even how that helps us determine who did the shooting.

Be my guest.

Nice try, but several witnesses reported the second and third shots as a "bam-bam" and stressed they were "very close together" (Lee Bowers, et al). If Oswald or any other human was operating the "humanitarian rifle", they would have to cycle the bolt after the second shot and reacquire the target AND fire accurately. Can anyone honestly say that there's such a thing as two shots "very close together" from a bolt action rifle? I think not...

I started this thread knowing there would be many who would concoct scenarios to fit the discredited SBT. But the extent to which folks twist the evidence reminds me of trying to have an intelligent discussion with a Trump supporter. I will state it again because I'm an ineffective communicator. The single bullet theory is impossible because no shots exited from the front of the president's body. Several witnesses saw the president before the SBT could be fabricated. They report the throat wound as one of entrance. End of ballgame for SBT, just from a different direction!

I read that HSCA testing showed the rifle could be fired twice in 1.67 seconds. The catch is that the second one of the two shots missed; only the first could be aimed precisely. I would contend that even just pointing at the target still leaves open the possibility that the shooter could have scored the headshot due to pure dumb luck.

And the Warren Commission surely used multiple choice tests for their interrogations. You can't be serious, can you?

BTW, the book you quote actually supports my point of view on witness testimony, as it focusses on the fallability of such testimony. Quoting a part of the book and neglecting the rest is nothing else than quote mining!

No, it is indeed vice versa! Witness testimony is actually quite unreliable, I think the Wikipedia article on eyewitness testimony  is a good starting point for your own research on that topic.

Really?

I would guess it was either the second or third. I wouldn’t say definitely on which one.

I believe that it was the second shot, so I heard the third shot afterwards.

That's not knowing to me, that's guessing!

Futhermore: Tague testified, that there was a fresh bullet mark on the curb.

About 12 to 15 feet right on the top of round of the curb, was the mark that very definitely was fresh, and I would say it was a mark of a bullet.

This contradicts your hypothesis, that all bullets hit Kennedy and/or Connally. Why do you exclude this part of his testimony?

Well, there is no evidence for your hypothesis of three shots that hit, but there is evidence for a shot that didn't hit. So your hypothesis seems quite impossible.

The Warren Commission (yes, they indeed got something right!).
 

And I am still waiting for a conspiracy buff to demonstrate that the single bullet is not possible.
 

In contrast to conspiracy buffs, the "lone nutters" did experiments and proved, that the single bullet indeed was possible.

That's a very lousy attempt of shifting the burden of proof and actually wrong! You cannot prove, that something doesn't exist, but you can prove, that something didn't happen.

Example: I can prove easily, that the Las Vegas Knights didn't win the Stanley Cup in 2017, because they joined the NHL for the season 2017/18.

It is new to me, that a fireball bursted out of Kennedy's head, I always thought it were brain tissue and blood.

Which bones were hit by the bullet?

As I am well aware of the geometrical problems involved, I won't do that. Your analysis is doomed to fail, because your approach is flawed. A line drawn on a two dimensional picture does not reproduce the angle in the three dimensional environment.

OT, but nevertheless totally impossible.

In contrast to conspiracy buffs, the "lone nutters" did experiments and proved, that the single bullet indeed was possible.

Show the CT side or demonstrate.
