I am seeing various "the shooting is fake" videos out there. I applaud them. But some of the so-called experts pointing out the "inconsistency" of the sound of the would be assassin's gun and the SS snipers on the roof have a Hollywood idea of what a long range gunfight sounds like.
In short, from about 150 yards or so, the bullet hits before you hear the sound of the mini-sonic boom, or the crack of the bullet in the air. Why? Because the bullet moves faster than the sound.

Which isn't much time at all.
I'm not checking the math, but it's still the reason why people are wondering why they see Trump react before the camera, even further away, registers the sound, and further, why they hear the sound of the return fire when they do.
