Question No. 6: “Did you see Oswald in the Dallas jail on Friday night?” Mr. Ruby replied “Yes.”
Question No. 8: “Did you have a gun with you when you went to the Friday midnight press conference at the jail?” Mr. Ruby replied “No.”
There was one other question asked which I consider irrelevant. However, it is of value to the series, and I will make mention of it, question No. 9: “Is everything you told the Warren Commission the entire truth?” Mr. Ruby responded “Yes.”
With regard to overall interpretation of series No. 7, I first noticed there is a physiological deviation to Mr. Ruby’s response to question No. 1 which was “Do you intend to answer the questions truthfully.” However, my notes indicate that Mr. Ruby talked and said “Yes, I do,” and by actually speaking several words it is believed that this caused the variation in the tracings.
Mr. Specter. Will movement or speaking cause a variation in the tracings ordinarily, Mr. Herndon?
Mr. Herndon. Yes. Body movements or speaking any phrase or sentence would certainly cause changes in the physiological patterns as displayed on the polygraph. I made notation of that, however, and that explains the changes. On question No. 2, Mr. Ruby did show a significant drop in the relative blood pressure. This question pertained to: “Did you go to the Dallas police station at any time on Friday November 22, 1963, before you went to the synagogue?” I asked him about this question later when he responded “No,” and I noticed a physiological change. He advised that there was some man by the name of John Rutledge, and he made an association with proceedings at the trial which I have reason to believe this gentleman, John Rutledge, differed somewhat with what Ruby stated as to when he went to the synagogue.
Due to the nature of this change, however, it is possible that it was caused by a body motion that I failed to detect during the actual response.
I notice that the cardio pen dropped all the way down and hit what we call the limit screws. This frequently is caused by a sudden rapid shift in his body position, and this change could have been caused by a body movement.
With regard to the other relevant questions in this series, question 4, question 6, and question 8, there was no significant deviation from his normal physiological patterns.
Mr. Specter. Were there any other significant findings, in series No. 7?
