You're so full of beans I can smell you from here.

I choose to believe the witnesses whose account jibe with the Z-film which is probably a minority of the witnesses.

When you say "the preponderance of all the rest of the evidence" you really mean the preponderance of the witnesses accounts of the shooting. You rarely if ever offer hard evidence to support you beliefs. Since you seem to place most of your faith in the witnesses over the forensic evidence, explain this:

How do you suppose 38 earwitnesses pointed to the same wrong location as the source of the shots? Did these witnesses corroborate each other?

That is pretty simple to explain because humans perceive sound direction not source direction.

The perceived direction of a sound is something your brain figures out by itself from the time difference between the arrival of a sound wave front at the left ear and the arrival of that same wave front at the right ear.  The brain then interprets that to be the same direction as the source. That is how we evolved. And on the buildingless, treeless African savannah that was a pretty good way to determine the sound source. The problem is that this time difference is skewed if sound wave fronts are arriving from multiple directions.
 
In Dealey plaza with all the concrete surfaces including large pillars and curved pergola walls, the direction of the sound waves was not necessarily the direction of the source of the sound: the SE 6th floor TSBD.

So there were many witnesses whose brain was confused about where exactly it appeared the sound came from.  Few of those far away from the corner of Houston and Elm could identify a specific location of the source. Within those 38 witnesses there is a large range in where they thought the shots came from.  Many admitted confusion about where the sounds came from e.g. Powers thought it came from his right or from the underpass. Mary Woodward also thought the sounds came from “possibly behind her” or from the right where the underpass was located.

The fact that the witnesses in different locations differed on where they perceived the source was located but almost all thought three shots appeared to them to come from the same direction tells you that the sounds reaching their ears came from more than one direction and those directions differed depending on where the witness was located

Thank-you for providing an excellent example from the “I can’t win the argument so I will resort to the ad hominem approach” school of rhetoric.

It's all earwitness evidence and it is all subject to error by large numbers of people. Anyone who bases their beliefs primary on what earwitnesses said has a very shaky foundation.

So you must have absolutely no confidence in the accuracy of any memory that you have.
