I was mistaken....and in error .....The SE corner of the TSBD is not behind Chaney's helmet.....
How did you establish the angle for the red line, from the right front corner of the Lincoln to the point on the north curb of Elm street?
Using the photo and shadow of the right side of the Lincoln as base .......the red line is at about 162 110 degrees , but on your drawing the red line is at about 110 162 degrees in reference to the side of the Lincoln.
HI Paul - Altgens 6 (A6) is supposed to be taken at z frame 255 -So the question is:
Is Officer Chaney along side the presidential limo in Altgens 6? - and is A6 actually taken around z255?
Here he is in Altgens 6 (motorcycle Officer Chaney all the way left)
I cut this piece of A6 out so you can see the small piece of Chaney's shadow just to the left of the limo and the lane markers to the right.
Zframe 255 does not show Chaney at all
You are correct Mike.... Which is stark evidence that the Z film is a fraud.....
