Even the most supportive of his minions are saying it was a bit of glass from the teleprompter that clipped his ear. No one is actually claiming it was a bullet. I grieve for those who were wounded and the one that died just so trump could look tough.
I think the blood was real. He or one of the agents clipped his ear so he would have blood on his face to look “defiant” for the picture they planned to take. But the tip of the ear while it bleeds is less damaging than a paper cut.
Then why would what I wrote be odd? At that range, with that weapon and he doesn’t even come close to trump? That’s what’s odd.
