OK,
I think we are going to come to an agreement sooner than expected!
I had an alternative way to check the notches positoin and have to admit that you are right, the fence with the notches is exactly offset by one fence to the bullet trajectory. I therefore have to retract this hypothesis and apologies to everyone. I lost a lot of credibility on this one.
Thank you for having gone on site so that we could clarify this topic. So: Notches into the red zone!
Just before we bury this topic, the only explanation about these strange notches being so close to the trajectory could be the following:
@kwaka in this post noticed that the complete Trump rally layout footprint was turned by 3 -5 °mentioning that they turned the layout to get a better position to shoot?
So, could it be that the first position they had, was in line with the notches, but after words having noticed that there is a potential collision with the left bleachers and the fence, they decided to change the layout for a better shooting position? Something we should ask the Trump setup team who helped build up the stage: did they have to suddenly change the layout for unknown reasons?
