Anyway, if I were retained to construct a plausible conspiracy to sell to a jury or the court of public opinion, I believe I would have to work within these realistic parameters.
Humm, well, since 2/3 to 3/4 of the Western world finds your theory of the JFK assassination to be implausible, perhaps you should focus on coming up with a plausible lone-gunman theory. Here are just a few of the markedly implausible aspects of the lone-gunman story:
-- Your supposed lone gunman, Lee Harvey Oswald, who was at best a mediocre shot when using a semi-automatic rifle against stationary targets at Marine rifle ranges, allegedly used a bolt-action rifle to perform a shooting feat that has never been duplicated, not even by Master-rated riflemen who used the alleged murder weapon and who fired under easier conditions than those Oswald would have faced.
Not one of the rifle tests that have been done to date have duplicated all of the conditions under which the supposed lone-gunman would have had to fire. In the one rifle test that duplicated most of those conditions, the 1967 CBS rifle test, only one of the 12 riflemen scored two hits in the required timeframe on the first attempt, and that was only because the test counted shots as "hits" even if they landed far down on the back or far out on the shoulder of the target silhouette, at least tripling the size of the target compared to Oswald's alleged shooting feat.
-- You can't even identify when Oswald could have zeroed the alleged murder weapon. Some of you have even floated the absurd argument that the rifle would not have needed to be zeroed, a spurious notion that even WC staffer Wesley Liebeler scorned in an internal WC memo.
-- You have your supposed lone gunman shooting from the sixth-floor window when multiple eyewitness accounts (1) independently put him on the first and second floors of the building during the shooting, and (2) rule out the claim that he dashed down the stairway in time to be seen by Officer Baker beyond the second-floor landing's door to the lunchroom.
-- Your alleged lone gunman went to the trouble of carefully hiding his rifle but left his paper "gun case" and his three spent shells in plain view near the sixth-floor window.
-- Your supposed single assassin allegedly ordered his rifle by mail, idiotically and needlessly creating a paper trail that led straight back to him, when he could have easily bought a better rifle at a local gun store that would have been untraceable (there was no gun registration in Texas in 1963). Not only this, but he mail-ordered the rifle using name Hidell (although no Hidell was listed as authorized to get mail from his post office box), and then, incredibly, carried a fake Hidell ID card on him on the day of the shooting!
Oswald was no fool and was not ignorant. He was highly intelligent. He spoke fluent Russian. He was a voracious reader. Oswald’s tested IQ scores generally ranged from 103 in the fourth grade to 118-119 on subsequent tests. His 118-119 scores put him in the above-average category. Historical and psychiatric evaluations consistently classified his overall intelligence as above average. Says British scholar Anthony Summers,
. . . evidence suggests Oswald was far from stupid. School records show that in several subjects he was three years ahead of his class, and his intelligence was noted by his officers in the Marine Corps. (Not in Your Lifetime: The Defining Book on the JFK Assassination, p. 77).-- You have your supposed lone gunman using the wrong kind of ammo to have caused the bullet fragmentation seen on the JFK autopsy skull x-rays. This isn't even a close call. No FMJ bullet would have exploded into dozens of tiny fragments and several sizable fragments, in addition to depositing a large fragment, two small fragments, and several tiny fragments 1 cm below its alleged entry point. Such behavior for FMJ bullets is unknown in forensic science. Revealingly, the HSCA's medical panel declined to cite a single case where an FMJ bullet had behaved in this manner, even though they knew this was an issue.
Again, these are just a few of the implausible claims of the lone-gunman theory.
