Whether you want to get shot or not, it is imperative that you obey a cop’s ordinary demands. We used to know this when I was growing up. I saw nothing unusual in the cop’s questions or demands.
If my failure to not instantly comply with a police officer means that police officer is entitled to kill me then we’re overdue for a revolution.
And I saw nothing unusual with the officer’s requests up to the point he unlocked the car door. Given how fast he came up with his pistol it seems to me he had his hand on it as he opened the door.
In which case the driver had justifiable cause to fear for his life, didn’t he?
