she tried to run over the cop and/or thats what he thought when he fired, anyway

Even if this was true, it's honestly irrelevant. You're not supposed to fire upon the driver of a running/moving vehicle period, lest the vehicle become an 'unguided missile' (via dead weight pressing on the accelerator) that can cause who knows how much more damage.

ICE's own rules explicitly prohibit it, I saw someone citing them earlier.
