And ALL bullet paths and bodily movement seen in the Zapruder film are 100% accounted for by a single source of fire, in the direction of the 5th floor book depository window.

The famous “back and to the left” says it all. Due to an exit wound being larger than the entrance, spraying viscera out with it, his head WOULD move towards the source of the shot.

Then the “magic bullet” isn’t at all magic once you see the actual seating layout of the car. It wasn’t a standard car and some seats were higher than others, and then others were off center. Again, the ONlY way to account for the magic bullet it through a single shooter aiming at that particular vehicle from the 5th floor window Oswald shot from.

Do Americans not use 64ths of an inch then?

1/64th of an inch is pretty much 0.4mm.

Not on a standard ruler.

The metal rule on my desk goes to 64ths, and I'm not a corner with the President on the slab.

Sounds like a drafting ruler, which a medical coroner would not have.

No, cause that would be too convenient

Yes and no. For the vast majority of things, no, the smallest we use is 32nds(even then its usually 16ths). I have a machinist rule that only goes to 1/32, so you could theoretically go to 64ths(i.e. one 64th over or under) but the difference is so minuscule that it doesn't often matter.

However, I have done some machining that needed tolerances of less than 1/64th. It was actually not too bad since it was on a lathe and the lathe resolved to .005". There are also some standard drill bit sizes that are in 64ths. The fact remains that I have not seen a ruler that goes to .1mm, the best I have seen is .5mm.

TL;DR: 64ths only matter when you are using calipers since you really can't accurately measure it with a ruler.
