Just to take one example from your litany of lame rationalizations, you say "Jackie moved [turned, to be more precise] her head [to her left starting at Z-145] to acknowledge the crowd."

Rhetorical question: Is that why she had a concerned look on her face as she was looking directly at Robert Croft in his well-known Z-161 photograph?

Seems like a strange way to "acknowledge the crowd."

Over 80 witnesses provided evidence that is inconsistent with a shot at that point. Even Croft said his photo was not only before the first shot, but he had time to wind his camera and get ready to take another before the first shot. So your insistence that they were all, independently, wrong but mutually consistent with each other because you can read her face is difficult to understand.  In any event, face reading is not a science and is nothing more than speculation with zero evidentiary or persuasive value.

By the way, you never gave a rational answer to my question:

Why did Secret Service Agent George Hickey lean so far over the side of the car, and when did he begin that motion?

Since there hadn’t been a shot, if he was leaning out it must have been to get a better look at something unrelared to a rifle shot, possibly people who were standing in the roadway.

Jefferson "Yuri Nosenko Was a True Defector" Morley's "JFK Facts" (sic).

Gag me with a KGB spoon.

What is obvious is the much higher "Burden Of Proof" required on this Forum.

That statement is contradicted by the fact that you and your CT ilk spew virtual diarrhea here several times a day.

The clearest reaction [to the first, missing-everything, shot] is JBC's head turn [back to his right] at Z-164. A shot at theoretical Z-124 would have been heard by him at theoretical Z-126. That's 38 frames, or just over two seconds.

Between Z-133 and Z-143, JFK is looking at the spectators to his right (and either waving to them or brushing his hair back), as is JBC, who is just looking at them.

In Z-143, JFK starts turning his head quickly towards Jackie and then turns it quickly back to his right, towards the spectators.

At Z-150, JBC quickly turns his head to his left about 45 degrees and is "captured" looking almost straight ahead in the Z-161 Robert Croft photo.

In Z-164, JBC starts turning his head quickly back to his right about 120 degrees to try to catch a glimpse of JFK over his right shoulder, but he can't "see" (i.e., recognize) him because by Z-180 JFK has turned his head far to his right and has raised his hand and forearm to wave to someone, thereby partially obscuring JBC's (peripheral) view of his face.

Point being: JBC consciously reacted to Oswald's "Z-124" shot about 1.31 seconds after hearing it, not "just over two seconds" after hearing it.

Interesting tidbit on LHO first crossing the border into Russia:

"There is also a curious snippet from a man named Bill Trousdale, who happened to share a train from Helsinki into Russia with LHO. Fellow Americans, the pair bantered a bit on the train.

According to JFK Facts, “Trousdale saw Oswald get special treatment from the Russian border guards: “At the border my bags were given pretty thorough going over,” Trousdale wrote, “but they scarcely looked at Lee’s.’”

Was LHO already a de facto KGB asset, and waved through the Russian border?

Some have posited LHO may have been working for CIA'er Bruce Solie, who is further posited to have been a KGB asset.
That is an interesting CT on JFKA-world.

So...how long did LHO remain a KGB asset? Was LHO a witting KGB asset? Did the KGB "lay off" LHO onto G2 or DGI??

Why was LBJ so concerned about LHO-Havana connections?
