Two separate West surveys, for SS and FBI.
They also indicate third shot/hit directly in front of Altgens. As does Altgens testimony. Note Altgens location, documented by...Zfilm.
This is the situation, as I understand it. Please correct me on any detail I get wrong as a lot of this is guesswork and assumption.
At the behest of the SS/FBI Robert West surveyed part of Dealey Plaza from which he created a Plat Map (a representation of the information gained from the survey, very often a drawing or series of drawings). West was then asked to project the impact points of three shots fired during the assassination.
In order to determine the impact points West had to be given at least three pieces of information concerning the shots:
The location from which the shots originated
The direction of each shot
Most importantly, as far as this thread is concerned, the timing of each shot.
None of this information could be magically deduced from a drawing of Dealey Plaza. West was given the information by the SS/FBI.
The only question of any relevance for this thread is - How did the SS/FBI determine the timings of the three shots at z207, z312 and z350?
I have asked you this question a number of times and you clearly don't know, but we can assume, as they were using z-frames, that the Zapruder film played a large part in their deductions.
Without knowing how the SS/FBI came to their conclusions about the timing of the shots you fully accept they are correct.
In this thread I have presented argument after argument leading to the conclusion that the first audible shot of three shots assumed to come from the TSBD occurred at z223.
You have not challenged any argument I've made, you've simply said West Survey, West Survey, West Survey.
You have fully accepted that the SS/FBI are correct and have refused to enter any kind of meaningful dialogue regarding the arguments I've presented.
Very early in this thread Joffrey made the point that z207 was a shot through the oak tree. Why do you accept this as being correct?
