I haven't posted it yet, but I did a full analysis on this. The thing is, proportionality still lies on the cops side, and it would probably be on the cops side no matter what, even if it wasn't a cop. When you try to run someone over with your car, or at least if someone believes that you are trying to run them over with your car, proportionality says you are already using deadly force, so using deadly force back is justified in defense. And I would push further, and say this isn't an America thing. If you try to run over a law enforcement officer in europe, or in the uk, or in japan, or in china, or in canada, pretty much every one of those places would consider that police officer justified in pulling their gun on you. You just don't have a right to run people over with your car. Don't do it, it's a bad idea. Earlier mountain_jay talked about the fact that the shooting wasn't necessary, and and I think that that's a separate question from whether it was justified. Legally and morally speaking, when that lady hit the gas when someone was immediately in front of her car, if she got shot it was her own fault almost anywhere. But I would tend to agree that this isn't like that white SUV that happened the same day where the guy turned around and went to run the cop back over three more times. I'm guessing that based on the fact that the police officer did survive, that things would have turned out much better if he hadn't. She would still be going to jail, but she would still be alive. But, that's something that's easier to say with perfect hindsight.
