He 'deliberately' left it out or he 'deliberately' didn't analyze
the physical evidence available to him.
In either case, it completely invalidates his other claims.

Of course you are skeptical, because analysis of the horizontal
angle completely disproves the possibility of JFK being shot
in the back from the TSBD 6th floor window.

I didn't use Wechts 38 degrees, I used a scale map of Dealey Plaza.
I also know JFK's position in relation to the limo, because
his body position is very clear in the Zapruder film.
I also used the latest possible position for him to be shot, around
the Zapruder frame 220 you claim.

If JFK had been shot from the 6th floor of the TSBD at Z 220 and
it impacted where the physical evidence shows , then the bullet
should have exitted well to the left of his windpipe.
It didn't, therefore I can conclude he wasn't shot from the TSBD.

We are not talking 'angels on the head of a pin'.
This is the kind of analysis that should have been done by the WC.
It wasn't or it was suppressed. Lattimer also left it out.

Nobody saw any rifles being fired from the TSBD either.
A shell casing was found on the roof of the County Records
Building many years later.
The grooves in the sidewalk alongside Elm, made by a bullet,
point back towards the Dal-Tex, not the TSBD.

I picked the shallowest angle possible. If the bullet was
fired earlier, it would have exitted even *further* to the left.

Bzzzzztttt. *Nobody* saw a rifle fired from the 6th floor of the
TSBD. Some witnesses saw a rifle in the window. *None* saw it fired.

Wrong. If this was analysis of the assasination, he should have
analyzed all possibilities. What Lattimer really did was set up
all his testing to prove Oswald did it. *None* of his testing
tried to disprove Oswalds involvement.
