The problem with conspiracy theories (indeed, arguably the definition) is the amount of of extra bollocks you need to start adding to keep the "fact" alive when the obvious questions are asked.
I have no doubt that there are inconsistencies in the narratives around well reported events. But that in and of itself proves nothing. And invariably when you start digging, you discover that the "smoking gun" never was.
Just for starters there is someone claiming that it was "impossible" for LHO to have aimed and shot 3 times with accuracy. So impossible that when the Warren Commission decided to put it to the test, a local sharpshooter was easily able to do it.
From Warren Commission on the timing of the shots —
It will be recalled from the discussion in chapter III that the assassin in all probability hit two out of the three shots … if either the first or third shots missed, the assassin fired the three shots during a minimum time span of 7.1 to 7.9 seconds. A series of tests were performed to determine whether the weapon and ammunition used in the assassination were capable of firing the shots which were fired by the assassin on November 22, 1963….
In an effort to test the rifle under conditions which simulated those which prevailed during the assassination, the Infantry Weapons Evaluation Branch of the Ballistics Research Laboratory had expert riflemen fire the assassination weapon from a tower at three silhouette targets at distances of 175, 240, and 265 feet. The target at 265 feet was placed to the right of the 240-foot target which was in turn placed to the right of the closest silhouette. Using the assassination rifle mounted with the telescopic sight, three marksmen, rated as master by the National Rifle Association, each fired two series of three shots. In the first series the firers required time spans of 4.6, 6.75, and 8.25 seconds respectively. On the second series they required 5.15, 6.45, and 7 seconds. None of the marksmen had any practice with the assassination weapon except for exercising the bolt for 2 or 3 minutes on a dry run. They had not even pulled the trigger because of concern about breaking the firing pin.
So: remove the "fact" that LDO could not have fired 3 shots in that time and the whole house of cards collapses.
I will wager a Christmas prosecco not a single loudmouth on that thread has read the Warren Commission report.
The only question we should permanently ask about everything, is: cui bono ? Because that usually leads you closer to the truth.
