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.

It was mentioned, and it was an important point to them at least, but whatever.
