I'm the anon that created the autism geometry image of the cameraman.
The only new detail since which I'm satisfied with is the asphalt area behind the curb is the exact same height as the grass in the venue, as revealed by the footage of them "taking his body away" in that vehicle, so that cameraman's feet can be assumed to be at the same level.
However, Charlie is seated on a small, slightly elevated stage which has been set up for the event, as seen with that security guard's brown shoe. I estimate it to be at or slightly lower than the average stair step, which would raise Charlie's seat ~5-7 inches higher than the ground.
The other major 3D detail in that area is that the security guard standing there signaling with his arm may be directly in the path of LoS between the cameraman and Charlie.
Honestly I think this mounted camera might be something to look into and to plot its potential firing vector. Its downward facing angle towards Charlie's seat would provide the high trajectory which the bullet captured on camera seems to have, and which would not risk hitting the crowd.
An assumption for whatever setup they were using for the true assassin's bullet would be that it simply could not hit an audience member after the shot, since such an injury after it hit Charlie would spoil the patsy narrative they'd meticulously set up to cover their tracks. It would have to be placed in such a way that it would kill Charlie but wouldn't risk hitting the crowd and revealing the whole operation.
I would attempt to find footage of this event prior to the actual shooting, since this camera is in a stationary position, and I haven't yet seen if it were mounted on some sort of gimbal to make other aim adjustments. We would be able to see its position after all of the sound and camera equipment has been set up.
At least two different angles of footage of the camera would be sufficient, since we could use Charlie's neck as the 3rd point for vector triangulation.
