This is not true, and it’s your fatal flaw. It’s a random event. No specific spot is any more likely than any other specific spot.
My mistake. Tague said that the patrolman who talked to him “saw something fly off back on the street". And then they saw a fresh mark there on the curb.
Isn’t that what you are doing — interpreting the marks you see on the curb as it now exists as tire rim marks?
You are referring to James Tague’s Warren Commission testimony:
Mr. TAGUE. Right. Going on Elm. So I stood there looking around. I looked up---there was a motorcycle policeman, and he stopped and had drawn his gun and was running up the embankment toward the railroad tracks. A crowd of people; several people, were starting to come down into that area where he was running, and the people pointing, and excitement up there and so on, and about that time a patrolman who evidently had been stationed under the triple underpass walked up and said, "What happened?" and I said, "I don't know; something."
And we walked up to the---by this time the motorcycle policeman returned back close to where his motorcycle was, and we walked up there and there was a man standing there. Seeing that he was very excited--I don't remember his name at the time I did have it on the tip of my tongue very excited saying he was watching the President and it seemed like his head just exploded. This was a couple or 3 minutes after this happened. And the patrolman said, "Well, I saw something fly off back on the street."
We walked back down there, and another man joined us who identified himself as the deputy sheriff, who was in civilian clothes, and I guess this was 3 or 4 minutes after. I don't know how to gage time on something like that.
First of all, this is second hand information. We don’t have testimony from the police officer saying this but just Mr. Tague’s recollection that this was said.
More importantly, Mr. Tague did not say the police officer said “I saw something fly back on the street from where you found the lead smear”. At the time, no one had found the lead smear, so the police officer could not have known about that. The police officer said
“and it seemed like his head just exploded” followed by
"Well, I saw something fly off back on the street." Most likely talking about seeing a part of JFK’s head, bone fragment or brain tissues, fly off and land on the street.
Question: What makes you think the policeman’s statement is about something flying back from the curb and not something flying back off of JFK’s head?
