The red line is the trajectory of the first bullet that allegedly grazed Trump’s ear. Assuming that the bullet passed closed enough by Trump’s right side of his face, which part of his face would the bullet have grazed? His cheek? The bottom of his ear? The top of his ear? Other?

See specifically the part about abductive reasoning. This aspect of critical thinking should move you in the right direction and help you let it go sooner than later. Grasping at straws while ignoring mountains on top of mountains of concrete evidence might be fun to think about for a while, but there's so much other beauty in nature to get fixated on, if only you'll let go of obsessiveness and look outward.
This is deductive reasoning unless you want to contest the law of physics. Are you suggesting we have another case of "magic bullet" in which the bullet suddenly changed its direction mid-air?
