Date: Mon, 14 Dec 1998 18:26:24 -0600 (CST) From: james fetzer To: email@example.com Subject: TWENTY QUESTIONS ABOUT A RECENT POST A recent post from Art and Margaret Snyder--which may be found on the web site, namely, http://www.pe.net/~atd/zapr-2.htm--reflects a number of elementary mistakes in presenting a critique of the work of David W. Mantik published in ASSASSINATION SCIENCE. I would like to raise some of the issues involved here in an effort to elevate the sensitivity of this group to scientific and mathematical issues that may arise in the study of the assassination of JFK. Those who look at this study ought at the very least to ask themselves the following very basic questions: (1) According to Snyder, Josiah Thompson has described Mantik's argument --that the improbability of every member of a group of ten eyewitnesses being wrong, when there is only a 2% chance of each one being wrong, is 10 to -17, which is a very small number--as "loony". What does "loony" mean within this context? Is this a clear and precise scientific term? (2) According to a table reprinted in this article, which is drawn from Elizabeth Loftus, EYEWITNESS TESTIMONY (1996), p. 27, which in turn is based upon an article by Marshall et al. in THE HARVARD LAW REVIEW 84 (1971), p. 1620, when the salience of an observation is greater than 50%, the accuracy and completeness of the observations by the participants in the study of 151 observers of a movie was accuracy 98%/completeness 98%. What was their percentage of inaccuracy? percentage of incompleteness? (3) According to the Snyders, there are two kinds of statistical errors that can occur: Type I errors, which are false negatives (in this case, failing to see the limo stop when it did stop) and Type II errors, which are false positives (in this case, seeing the limo stop when it did not). Since Mantik's study is based upon reports of a limo stop by fifteen or more witnesses, which kind of error--Type I or Type II--is relevant here? (4) With different sized populations of observers, of course, the proba- bility of inaccuracy or incompleteness may vary. If the probability of inaccuracy by N-membered groups were .02 (.03, .05, .10, .20, .30, .40, or .50), for example, how would the improbability that they were wrong --all of them, since they are making identical reports--be calculated? 10 (5) The Synders state, "10 to the -17 = (.02) is the probability that 10 witnesses each with an independent (uncorrelated) 2% probability of failing to correctly observe an event (e.g., a "limo stop") would ALL fail to correctly observe it! It is the probability they would ALL say it had not stopped when it had stopped." Is this the right hypothesis to consider in this case? If not, what would be the right probability? (6) They continue their remark by stating, "It is NOT the probability of finding a group of 10 or so witnesses all saying the same wrong thing, e.g., the limo stopped when it did not stop." But is the probability of FINDING a group of 10 or so witnesses all saying the same wrong thing a relevant question here? Are we LOOKING FOR groups of witnesses here? (7) The Snyders concede that there is a conflict between the eyewitnesses who say the limo stopped and the Zapruder film, which does not show it. They suggest we must consider two hypotheses to explain this conflict: I. The film has been altered. II. The witnesses are mistaken. They claim that, "to compare these two hypotheses, we need the probabil- ity that this conflict could have arisen under each hypothesis". They then claim that "For the film alteration hypothesis (I) the probability is small but not computable". What is the source of this "probability"? (8) They also claim, "The relevant probability for the mistaken witness hypothesis (II) is the probability that a group of witnesses (large enough to catch our attention) would turn up". But hasn't a group of witnesses (large enough to catch our attention) ALREADY "turned up"? And if that is indeed the case, why do they say, "The probability that a specific group of witnesses is mistaken is IRRELEVANT. The relevant question is what is the probability of finding such a group. This probability is much larger."? If they have been found, does not that probability = 1? (9) What about their comparison to a lottery? They claim, "It is like a lottery. The odds of any particular person winning are very small, but the odds of somebody winning are high. The limo stop witnesses are the winners in a lottery to attract the attention of alteration advocates. The odds of any particular group winning are small; the odds that some group would win are much higher!" But why are they even discussing the limo stop witnesses as "winners in a lottery to attract the attention of alteration advocates"? What sense does that make? Did they enter some lottery of which we are all unaware? What sort of comparison is implied? (10) They remark, "Given that the limo did slow down (losing 1/3 of its velocity in a fairly short time) and that the brake lights were on, it is not that surprising that some people thought it stopped or nearly stopped. The MMO [Marshall et al.] results have NO BEARING on the probability of this error being made. There is no reason it is as small as 2%." But is it not simply BEGGING THE QUESTION by taking for granted that the limo did NOT stop to make the assumption that the limo MERELY SLOWED without stopping? After all, it would have had to slow in order to stop, so what independent evidence supports their contention that it MERELY SLOWED AND DID NOT STOP? Wouldn't it be likely that some people would only see it slow EVEN IF IT STOPPED? What could possibly justify their assumption? (11) They also claim, "If there were 250 witnesses in a position to see the limo stop, a false positive rate of 2% gives an expected number of false stop reports of 5. The probability of 10 or more false reports would be about 3%. Given the ambiguity of the situation the false pos- tive rate could easily have been larger than 2%." But where do they get the idea that there were 250 witnesses "in a position to see the limo stop"? Josiah Thompson lists more than 250 witnesses to some as- pect of the assassination in SIX SECONDS IN DALLAS (1967), pp. 254-271. Are they assuming that all of them were "in a position to see the limo stop" if it did stop? Is that a very reasonable assumption to make? (12) Thompson also provides a map of the location of these witnesses in his book on pp. 252-253. Anyone who takes a look will see that the witnesses are asymmetrically distributed around Dealey Plaza and that most of them would have been ill-positioned to have observed the limo stop, if it had stopped. This point was made during David W. Mantik's presentation at Lancer in Dallas by presenting an overhead that marked the location of the witnesses whose testimony he was discussing. Is it just a bit disingenuous of the Snyders to fail to report that fact? Would not the location of these witnesses make a crucial difference? (13) They say any probability analysis done "after the fact" is poten- tially subject to large selection biases. Why is that? Does the out- come of a toss with a coin change after it has been tossed? If it was a fair coin, did it not have a 1/2 probability for heads and 1/2 prob- ability for tails even after it has landed? Should sports teams object to the use of tosses of coins to determine who kicks off and who re- ceives because the outcome of the toss of a coin is "after the fact"? (14) If studies of salience substantiate high degrees of accuracy and completeness under relatively controlled conditions, why should these results not be extrapolated into uncontrolled situations, especially when the are sufficiently like those controlled situations? The Sny- ders claim the 2% chance of being wrong was "ripped out of context". But take a look at the description of the test situation, which was a two-minute long movie with over 900 items of interest. Is there no basis of comparison, even though the number of observers is presumably smaller in the case of the assassination than in the case of the film? (15) They say, "If the probability of JFK assassination witnesses to fail to see a stop that actually occurred were as small as 2% it would virtual- ly rule out a stop having occurred!" But is this not a claim that is be- ing made about false negatives, when it should be about false positives? And is it not another way of concealing the extremely low probability of witnesses in this case being wrong in their actual reports of a limo stop? (16) Why don't they say, "If the probability of JFK assassination witnes- ses to see a stop that actually did not occur were as small as 2%, that would virtually rule out a stop not having occurred!" After all, what Mantik has produced and Palamara has confirmed is a large number of wit- nesses who report that the limo stopped, not a large number of witnesses who report that it did NOT stop. Are the Snyders assuming that everyone who did not report the limo stopped counts as reporting that it did not? Would that be a reasonable assumption to make? If so, why? If not, why? (17) According to the Snyders, "The data is inconsistent with a 2% "chance of be(ing) wrong" and the limo actually stopping!" But why do they say such a thing? Isn't the data CONSISTENT with a very small chance of be- ing wrong and the limo actually NOT stopping? What kind of game is be- ing played here? After introducing the difference between Type I and II errors, they persist in framing every question in terms of Type I errors. Are they talking about the RIGHT KIND of error? But isn't that Type II? (18) They not only say that the 2% chance of being wrong was "ripped out of context" but "It is not applicable to any real world situations much less the JFK assassination." Does that mean that it does not even apply to the 151 witnesses who observed the two minute film? Was that not "a situation in the real world"? Why are they making claims of this kind? What is the point of studying eyewitness reliability if not because it has relevance to real world situations when it is appropriately applied? (19) According to Elizabeth Loftus, "It is fair to say that salient de- tails are remembered better than peripheral ones. Also, it is easier to mislead people about peirpheral details. It is WRONG, however, to say anything like 98% of salient details are accurately remembered. If that was shown in the Marshall case, it is only with those subjects, with that stimulus material, in that study. We virtually never make claims about absolute percentages because the real percentages in any situation depend on so many other factors." But even if the difference were such that the chance of being wrong was 5% instead of .02%, the improbability that ten witnesses reporting a limo stop were all mistaken would = .5 to the 10th, which is approximately 1/1024 or about .001, which is a very small number. So what is wrong with making extrapolations to similar situations, even if the ABSOLUTE PERCENTAGES would vary with the relevant circumstances? And in fact was not the scene the assassination witnesses observed actu- ally LESS complex and LESS prolonged than the Marshall study situation? (20) The Snyders conclude with the announcement, "Tink was right!" Is that an appropriate conclusion to draw based upon the analysis that they have provided? Does their analysis support their conclusion? Remember that Tink's conclusion was that Mantik's analysis was loony! Given the considerations adduced above, was his analysis loony? How about Tink's? Jim BONUS QUESTION: How many people were "some people" who thought that the limo had stopped? (Consult the valuable study by Vince Palamara below.) Normally, you would assume that someone would report a limo stop BECAUSE the limo had stopped. What do the Snyders suppose they would report IF THE LIMO HAD stopped? Would they have reported that it had NOT stopped? __________________________________________________________________________ On 13 Dec 1998 Vincent Palamara wrote: Subject: "59 Witnesses: Delay on Elm Street" 59 WITNESSES: DELAY ON ELM STREET By Vince Palamara Updated 1998 edition (based off the original 1991 article "47 Witnesses" that appeared in "The Third Decade", Jan/ March 1992, and which has since been cited in "The Third Decade"[11/92], "The Fourth Decade[11/93 and 9/97], "Proceedings of the Second Research Conference of the Third Decade, 6/18-6/20/93", pages 128 & 162, "The Proceedings of the Research Conference of the Fourth Decade, 7/19-7/21/96", p. 277, "The Third Alternative-Survivor's Guilt: The Secret Service and the JFK Murder" , pages 20& 53, the website "The Puzzle Palace", "Assassination Science" , p. 274, "Bloody Treason" , Z-frame 313 photo section, "November Patriots" , p. 465, and the 1998 revised version of "High Treason", p. 551) -UPI's "Four Days" (1964), p. 17---In the right hand picture [a frame from the Muchmore film], the driver slams on the brakes and the police escort pulls up." -"Newsweek", 12/2/63, p. 2---"For a chaotic moment, the motorcade ground to an uncertain halt." -"Time", 11/29/63, p. 23---"There was a shocking momentary stillness, a frozen tableau." -"Case Closed" by Gerald Posner (1993), p. 234---"Incredibly, Greer, sensing that something was wrong in the back of the car, slowed the vehicle to almost a standstill."

It seemed to him that the automobile almost came to a halt after the first shot^┼After the third shot, the car in which the President was riding increased its speed and went under the freeway overpass and out of sight." [22 H 837-838]; 52) Mary Moorman---"She recalls that the President's automobile was moving at the time she took the second picture, and when she heard the shots, and has the impression that the car either stopped momentarily or hesistated and then drove off in a hurry." [22 H 838-839]; 53) Jean Hill---"^┼The motorcade came to almost a halt at the time the shots rang out and I would say it [JFK's limo] was just approximately, if not---it couldn't have been in the same position, I'm sure it wasn't, but just a very, very short distance from where it had been. It [JFK's limo] was just almost stunned." [6 H 208-209; Hill's testimony on this matter was dramatized in the Oliver Stone movie "JFK" (1991): "The driver had stopped-I don't know what was wrong with that driver." See also "JFK: The Book of the Film" (1992), p. 122. Therein is referenced a March 1991 conversation with Jean Hill.]; 54) James Leon Simmons---"^┼The car stopped or almost stopped." [2/15/69 Clay Shaw trial testimony; "Forgive My Grief Vol. III" by Penn Jones, p. 53; "High Treason" by Groden & Livingstone (1990 Berkley Edition), p. 22]; 55) Norman Similas---"^┼The Presidential limousine had passed me and slowed down slightly." ["Liberty" Magazine, 7/15/64, p. 13; "Photographic Whitewash" by Harold Weisberg (1967), p. 233]; 56) Presidential Aide Ken O'Donnell (rode in the follow-up car)---"^┼If the Secret Service men in the front had reacted quicker to the first two shots at the President's car, if the driver had stepped on the gas before instead of after the fatal third shot was fired, would Presdient Kennedy be alive today? [as quoted in Marrs' "Crossfire", p. 248, based off a passage from O'Donnell & Powers' book "Johnny, We Hardly Knew Ye"] On page 40 of O'Donnell's book "Johnny, We Hardly Knew Ye", the aide reports that "Greer had been remorseful all day, feeling that he could have saved President Kenendy's life by swerving the car or speeding suddenly after the first shots." Indeed, William E. Sale, an airman first class aircraft mechanic assigned to Carswell AFB and who was stationed at Love Field before, during, and after the assassination, stated that "when the agent who was driving JFK's car came back to Air Force One he was as white as a ghost and had to be helped back to the plane *[undated Sale letter, provided to the author by Martin Shackelford]; 57) Presidential aide Dave Powers (rode in the follow-up car)---"^┼At that time we were traveling very slowly^┼At about the time of the third shot, the President's car accelerated sharply." [7 H 473-475]. On 11/22/88, Powers was interviewed by CBS' Charles Kuralt. Powers remarked about the remorse Greer felt about not speeding up in time to save JFK"s life and agreed with Kuralt that, if Greer had sped up BEFORE the fatal head shot instead of afterwards, JFK might still be alive today [CBS, 11/22/88---this is a very dramatic and compelling short interview]. If that weren't enough, the ARRB's Tom Samoluk told me that, during the course of an interview he conducted in 1996 in which the Board was in the process of obtaining Powers' film, Powers said that he agreed with my take on the Secret Service!; 58) Texas Senator Ralph Yarborough (rode in LBJ's car)---"^┼When the noise of the shot was heard, the motorcade slowed to what seemed to me a complete stop (though it could have been a near stop)^┼After the third shot was fired, but only after the third shot was fired, the cavalcade speeded up, gained speed rapidly, and roared away to the Parkland Hospital."; "^┼The cars all stopped. I put in there [his affidavit], 'I don't want to hurt anyone's feelings but for the protection of future Presidents, they [the Secret Service] should be trained to take off when a shot is fired." [7 H 439-440; "Crossfire" by Jim Marrs (1989), p. 482; see also "The Men Who Killed Kennedy" 1988: "The Secret Service in the car in front of us kind of casually looked around and were rather slow to react."]; 59) First Lady Jacqueline Kennedy (rode in the Presidential limousine)---"We could see a tunnel in front of us. Everything was really slow then^┼[immediately after shooting] And just being down in the car with his head in my lap. And it just seemed an eternity^┼And finally I remember a voice behind me, or something, and then I remember the people in the front seat, or somebody, finally knew something was wrong, and a voice yelling, which must have been Mr. Hill, "Get to the hospital," or maybe it was Mr. Kellerman, in the front seat^┼We were really slowing turning the corner [Houston&Elm]^┼I remember a sensation of enormous speed, which must have been when we took off^┼those poor men in the front^┼" [5 H 179-181] Mary Gallagher reported in her book: "She mentioned one Secret Service man who had not acted during the crucial moment, and said bitterly to me, 'He might just as well have been Miss Shaw!'" ["My Life With Jacqueline Kennedy" by Mary Barelli Gallagher (1969), p. 342---Secret Service Agent Marty Venker and Jackie biographer C. David Heymann confirm that this unnamed agent was indeed Greer ("Confessions of an Ex-Secret Service Agent", p. 25; "A Woman Called Jackie", p. 401)] Jackie also told Gallagher that "You should get yourself a good driver so that nothing ever happens to you" [Ibid., p. 351] * William Manchester, who interviewed Greer, tells us what the driver told Jackie on 11/22/63 at Parkland Hospital: "Oh, Mrs. Kennedy, oh my God, oh my God. I didn't mean to do it[?!?!], I didn't hear[who, Kellerman?], I should have swerved the car[how about hitting the gas!], I couldn't help it[!]. Oh, Mrs. Kennedy, as soon as I saw it[?] I swerved. If only I'd seen it in time! Oh!" (Manchester, p.290). 59 witnesses (10 police officers, 7 Secret Service agents, 37 spectators, 2 Presidential aides, 1 Senator, Governor Connally, and Jackie Kennedy) and the Zapruder film document Secret Service agent William R. Greer's deceleration of the presidential limousine, as well as his two seperate looks back at JFK during the assassination (Greer denied all of this to the Warren Commission-2HGREER[see his entire testimony]). By decelerating from an already slow 11.2 mph, Greer greatly endangered the President's life, and, as even Gerald Posner admitted, Greer contributed greatly to the success of the assassination. When we consider that Greer disobeyed a direct order from his superior, Roy Kellerman, to get out of line BEFORE the fatal shot struck the President's head, it is hard to give Agent Greer the benefit of the doubt. As ASAIC Roy H. Kellerman said: "Greer then looked in the back of the car. Maybe he didn't believe me"("The Death of a President" by William Manchester, p.160). Clearly, Greer was responsible, at fault, and felt remorse. In short, Greer had survivor's guilt. But, then, stories and feelings changed. Agent Greer to the FBI 11/22/63: "Greer stated that he first heard what he thought was possibly a motorcycle backfire and glanced around and noticed that the President had evidently been hit [notice that, early on, Greer admits seeing JFK, which the Zapruder proves he did two times before the fatsal head shot occurred]. He thereafter got on the radio and communicated with the other vehicles, stating that they desired to get the President to the hospital immediately [in reality, Greer did not talk on the radio, and Greer went on to deny ever saying this during his WC testimony]^┼Greer stated that they (the Secret Service) have always been instructed to keep the motorcade moving at a considerable speed inasmuch as a moving car offers a much more difficult target than a vehicle traveling at a very slow speed. He pointed out that on numerous occasions he has attempted to keep the car moving at a rather fast rate, but in view of the President's popularity and desire to maintain close liaison with the people, he has, on occasion, been instructed by the President to "slow down". Greer stated that he has been asking himself if there was any thing he could have done to have avoided this incident, but stated that things happened so fast that he could not account for full developments in this matter(!) [the "JFK-as-scapegoat" theme^┼and so much for Greer's remorse from earlier the same day!]."(Sibert & O'Neil Report, 11/22/63) Agent Greer to the FBI 11/27/63: "^┼he heard a noise which sounded like a motorcycle backfire. On hearing this noise he glanced to his right toward Kellerman and out of the corner of his eye noticed that the Governor appeared to be falling toward his wife [notice that Greer now mentions nothing about seing JFK hit---he does the same thing in his undated report in the WC volumes (18 H 723)] He thereafter recalls hearing some type of outcry after which Kellerman said, "Let's get out of here." He further related that at the time of hearing the sound he was starting down an incline which passes beneath a railroad crossing and after passing under this viaduct, he closed in on the lead car and yelled to the occupants and a nearby police motorcyclist, "Hospital, Hospital! [nothing about using the radio this time out]" Thereafter follows a complete physical description of Greer, as if the FBI agents considered him a suspect, inc. age, height, and color of eyes! (Sibert & O'Neil Report, 11/29/63) Critical excerpts from Greer's 3/9/64 Warren Commission testimony before Arlen Specter: Mr. Specter. Were you able to see anything of President Kennedy as you glanced to the rear? Mr. Greer. No, sir; I didn't see anything of the President, I didn't look, I wasn't far enough around to see the President. Mr. Specter. When you started that glance, are you able to recollect whether you started to glance before, exactly simultaneously with or after that second shot? Mr. Greer. It was almost simultaneously that he had--something had hit, you know, when I had seen him. It seemed like in the same second almost that something had hit, you know, whenever I turned around. I saw him start to fall. Mr. Specter. Did you step on the accelerator before, simultaneously or after Mr. Kellerman instructed you to accelerate? Mr. Greer. It was about simultaneously. Mr. Specter. So that it was your reaction to accelerate prior to the time-- Mr. Greer. Yes, sir. Mr. Specter. You had gotten that instruction? Mr. Greer. Yes, sir; it was my reaction that caused me to accelerate. Mr. Specter. Do you recollect whether you accelerated before or at the same time or after the third shot? Mr. Greer. I couldn't really say. Just as soon as I turned my head back from the second shot, right away I accelerated right then. It was a matter of my reflexes to the accelerator. Mr. Specter. Was it at about that time that you heard the third shot? Mr. Greer. Yes, sir; just as soon as I turned my head [^┼] Mr. Specter. To the best of your current recollection, did you notice that the President had been hit? Mr. Greer. No, sir; I didn't know how badly he was injured or anything other than that. I didn't know. Mr. Specter. Did you know at all, from the glance which you have described that he had been hit or injured in any way? Mr. Greer. I knew he was injured in some way, but I didn't know how bad or what. Mr. Specter. How did you know that? Mr. Greer. If I remember now, I just don't remember how I knew, but I knew we were in trouble. I knew that he was injured, but I can't remember, recollect, just how I knew there were injuries in there. I didn't know who all was hurt, even. Mr. Specter. Are you able to recollect whether you saw the President after the shots as you were proceeding toward Parkland Hospital? Mr. Greer. No; I don't remember ever seeing him any more until I got to the hospital, and he was lying across the seat, you know, and that is the first I had seen of him. Mr. Specter. Your best recollection is, then, that you had the impression he was injured but you couldn't ascertain the source of that information? Mr. Greer. Right. I couldn't ascertain the source. Warren Commission finding: "The driver, Special Agent William R. Greer, has testified that he accelerated the car after what was probably the second shot...The Presidential car did not stop or almost come to a complete halt after the firing of the first shot or any other shots."(WC Report, page 641) 11/19/64 interview with "Death of a President" author William Manchester [RIF#180-10116-10119]---"After the second shot I glanced back. I saw blood on the Governor's white shirt, and I knew we were in trouble. The blood was coming out of his right breast. When I heard the first shot, I had thought it was a backfire. I was tramping on the accelerator and at the same time Roy was saying, let's get out of here fast." But remember what Roy Kellerman said: "Greer then looked in the back of the car. Maybe he didn't believe me"("The Death of a President" by William Manchester, p.160). 2/28/78 HSCA interview [RIF#180-10099-10491]---"The first shot sounded to him like a backfire. He did not react to it. After the second shot he turned to his right and saw blood on Governor Connally's shirt. At the same moment he heard Kellerman say "We're hit. Let's get out of here," or words to that effect. He said he immediately accelerated and followed the pilot car to Parkland Hospital [However, DNC Advance man Jack Puterbaugh, who rode in the pilot car, said they "pulled over and let the motorcade pass" (HSCA interview 4/14/78). The Washington Post from 2/28/85 reported Greer as saying that "I just looked straight ahead at the car in which the police chief was leading our way to the hospital"---this is the lead car. Nevertheless, the Daniel film and still photos depict the limousine AHEAD of the lead car, as it appear it was the lead motorcyclists who actually guided Greer to Parkland! (see pp. 21-22 and 59 of "The Third Alternative" by the author)] Bill Greer passed away from Cancer on 2/23/85. The End?--- >From a 9/17/91 interview with Bill's son Richard: When asked, "What did your father think of JFK," Richard did not respond the first time. When this author asked him a second time, he responded: "Well, we're Methodists..and JFK was Catholic..." (Bill Greer was born and raised in County Tyrone, Ireland; 2 H 112 - 113) "My father certainly didn't blame himself; it's not one of those things - if only I was driving one mile per hour faster "My father had absolutely no survivor's guilt...he figured that events were kind out of their control...it was pretty common knowledge that a person riding in an open car was subject to a bullet at any time..." The End.
