Martin,
i am not too familiar with the BDM studies regarding his exact height or posture - i suppose you are.
If the studies show as you say and BDM was not standing straight but stooped then he was maybe just resting his /arms/upper body on the wall.
Or if he was indeed holding a long object then he was probably holding a rifle or an umbrella or a long yummy candy-cane... you can speculate and discuss this matter endlessly. Fact is that we don't know.
One logic explanation for BDM's instant dissappearance is that s/he hit the deck when the shots rang out.
Someone very close to the source of a shot would most probably react reflexively. Some people near the knoll also hit the deck. I don't know if any bystanders in close vicinity to the TSBD did that too although that was the area from where the shots were fired - if you believe the WCR.
liebe Grüsse, Gerda
Hi Gerry
Sure, i've spend some serious time on BDM and even began to create a 3D scene with the intention to navigate with your mouse
virtually around this retaining wall. As always my work was interrupted by my clients.
But i will finish it, hopefully.
I have so much on the task list and too little time to finish:
The scene inside the second floor. You know the encounter of Baker and Truly with Oswald.

Here a closeup of one box: LOL
The Backyard photographs.

The Retaing wall scene (which can cover many aspects like Badgeman, Gordon Arnold and also BDM)

A precise timeline of the footages and photographs shortly before and after the final shot....
all not finished. Sigh
I must confess that i have a tendency to divertion.
I mostly read 3 books on the JFK assassination simultaneously for instance....
If i would work out one after the other it would be better. But who knows for what this is good for.
I'am not 80 and therefore i see good chances to get it all done.
Back to your thoughts....
sure he could hit the ground like many others too in this area.
But you have to keep in mind that, in particular shortly after the fatal shot was fired many photographs and film footages were taken
by so many bystanders and professional photographers, that almost every second was captured on film within a minute after Z#313.
In no one BDM re appeared. Wilma Bond for example took a series of photographs within seconds after the limousine disappeared under the Triple underpass
covering exactly this area from vantage location. Willis took many photos after the HS covering this area....in no one is BDM. He is gone.
Where is he been gone so quickly?
I have an idea but it's a dangerous task to speculate on forums. Some are just waiting to discredit the enemy.
See Lee Farley and DVP or Mark Valenti and Anthony Marsh.
Sad but true.
I purchased today an original Life Magazine from November 24, 1967 which is covering a lot of well known photographs that day.
The seller told it's in good condition.
What i will do is to scan this photos with maximum resolution with the intention to contribute it to this great Photo Gallery (which is unique in it's form worldwide as i know) of this forum.
This will be a little payback to Robin Unger and Duncan MacRae.
This magazine covered also photos from Wilma Bond. I hope it will reveal something to support my theory.
As always my very best to you Gerry
Martin
