I thought of that, but even if it were flipped it would be pointing opposite his stance toward the crowd (as per the podium and teleprompter shadows), which is interesting but not probative.

Plus, all the photos of the crowd injuries (which all seem to be Comperatore) were taken from this same angle, left of the stage from the crowd's perspective. So I assume that's the same doctor prominent in other photos, and it wouldn't be flipped. But I'm still trying to confirm these details.
