Given the geometry of the venue, I think that would be the bullet after it had already struck President Trump.

Trump did a sudden head movement that rotated his head clockwise, this means that the bullet entry point would have hit the back of his skull and killed him instantly had he not.

yes that is the round already passed through his ear.
I believe this was a set up by the police and/or secret service.
Both the counter snipers were focused on that other roof. They where watching that shooter before he took the shot. Typically they're looking around.
