I have no idea if a crime had been committed by this individual. But I do know he walked to what I assume was his vehicle or one he’d been in and had repeatedly ignored verbal warnings. Most understand why the suspect could not be allowed to reach in, or quickly enter that vehicle. It’s pretty basic stuff. For all the cop knew, he could have swung open the door, grabbed a shotgun on the seat and opened up.
Why do you keep ignoring that he was shot on the ground?
