Bill Brown are you allergic to this lovely photo. Maybe you and Mytton get your info by way of horseback
Hahaha, in your first wave all I see is mostly a bunch of women who were going to hit the gunman/gunmen with their handbags? LOL!
Look closely at the whole picture and we see some people running to get off the road, some people standing about and some people in the distance who are just walking or standing, not particularly compelling.
A better representation of people running up the stairs is the following Bell Film but because of the edit we don't know exactly how long after the shots these people were running or why?
Here's panoramas of both Nix and Zapruder and there is hardly anyone this far down Elm street so where were the people who ran up the knoll and what did they see and/or hear?
