I see what you’re saying about the image at #721 ...the metal earpiece on the glasses of the the man behind the suspect seem to cover the edge of the suspects ear.
And look at the man with the straw hat ...the hat brim covers part of the “middle man’s” forehead, meaning the “middle man” would be behind the straw hat man — yet the “middle man’s” head appears to be 2 or 3 times bigger than the straw hat man’s head.
We enlarged it quite a bit, and the temple of the mans sunglasses not only cover the edge of his right ear, but goes far beyond the edge. And there appeared to be little movement in this shot.
In addition, look at the hair color of the mans hair immediately to the right of the suspects right ear, just above or at the very top of his ear. It appears the hair has been possibly manipulated and it’s in the same area as the temple of the glasses, again as if it had been manipulate and someone got sloppy in that area.
