Ray, Do you believe that the Lincoln passed behind the tree ...... Witnesses ( Vicky Adams and Sandra Styles to name a couple) on the fourth floor had no idea what had happened because the tree blocked their view....
This is what Andrew wrote, and what I agreed with.
"You just have to watch the film to see that it is taken from the TSBD. Not only that but you can watch as the car comes up Houston and see that Houston St. is to the east. If you aren't going to watch the film there is not much I can do."
As you said the witnesses were two floors lower than the sniper's nest, so the tree would probably have impeded their view.
