Walt, I get your intention now, I will do the LOS.
Yes Chaney's hand is seen next to Kellerman but he could be next to the limo or farther away along Altgens line of sight. Every single observation made by all of us has not resolved that basic issue of where along the LOS Chaney sits.
I do think because the camera is only one foot above the limo we should see way more of Chaney in the hood. I would think we would see him extend half way to the hood ornament.
