I’ve seen that picture. It doesn’t change the physics. The bullet fired at trump from 130 yards = 390 feet would reach him in ~0.13 seconds. The sound from that shot would reach him in ~0.347 seconds. He turned his head for another reason (divine intervention?) not because he heard the shot. Unless, the shot that hit him was a later shot.
That means the shooter would have to have fired the second shot - if it was the second shot and there were 4 shots fired - in ~.217 seconds. That would be very fast trigger work with the recoil from an AR (Assumed - I don’t know details on the weapon).
I’ve expanded my theory to include possible crowd shouting but when you watch the vid you can see several people behind PDJT turn their heads towards the shooter’s direction. They heard something.
And if you add Divine Intervention into the equation then...🙂
