IMHO - it is never reasonable nor responsible to assume.
There is not evidence that he was shooting to hit the driver at that point.
A vehicle is only a deadly weapon when it is pointed "at" someone? Then my handgun is not a deadly weapon.
I know it is argumentative and has no bearing, but how did he know she was unarmed? There is a good example of random, casual thought. The point of whether or not she was armed has not been introduced - do you know something that the rest of us do not?
Musing, declaration of "what ifs" as if fact IMO indicates a willingness to hear the case based on supposition.
I'm not hearing the case. I'm just engaging in casual commentary, and am not insisting in anything nor calling for judgment. I'll try to desist in posting random casual thought.
I do think that if I were the prosecutor, I would be inclined to ask the officer if he was intending to shoot the driver and the window. If I were the defense, I would be sure I knew what the officer's reply would be beforehand.
