That was very much my initial reaction.

( I'm outside the US, I've worked for deacdes in "intelligence" (being accurate about video, signals, resources, data) for well heeled private clients and state, national level governments. )

Wider angle earlier release video that showed the other officer approach the side window, reach in and attempt to grab keys and or unlock and open door (prompting car to reverse, turn wheels, and move forwards) show this officer turning, crouching, drawing, stalking in to aiming at driver all prior to the forward motion.

This released footage does not appear to have that sequence.
