Also, last night in his speech he described how the doctor said the ear bleeds a lot. None on his hand. None on the white cuff of his sleeve. Even as he drops to the ground after covering his ear, his hand is momentarily visible... no blood.
I am not positing a theory. I am asking about what looks like an inconsistency.
Also such an injury is not that easy to bandage so it probably was bleeding for quite a long time in the limo as they were getting him to a medic.
