(Save Pamela Ferrris sounds like K. H.)
I failed to find the horse lady footage again. Maybe it’s from Greg Smith, but he apperantly deleted the end of the vodeo. It might be interesting, there was a tripod at the east side just before the shooting, but the guy had no camera with him. And I was unable to locate that tripod on another bictures. Maybe he has better photos of the shooting. Also, Google reverse search cannot identify the individual.
Perhaps it is not interesting, just a random guy walked to the rally with a tripod. (For example, I often have a pockent lamp with me.)
