“Regardless of the cause, anybody approaching a person and appearing to be a potential threat needs to consider this. I don’t think a crime was committed in this video”
You think merely approaching a vehicle justifies making a lethal threat?
How about if you are passing a person in their car in a parking lot while walking to your car? You ok if they draw and point a gun at you for that?
Pointing a gun at someone is a lethal threat which could have reasonably been met with the use of lethal force. The driver looks like someone preparing to do a drive-by shooting.
Unless the person approaching his moving vehicle was also brandishing a gun or making some other overtly threatening action, what happened here was a criminal threat.
You have no idea what the person(s) approaching the car were doing.
