The officer’s decision to stand in front of her car may indeed be “against all common safety advice”. For your argument to prevail, however, you will have to go a little further. You will have to demonstrate that his actions were unlawful, or otherwise so egregious as to justify her deliberately moving her vehicle toward him. Unfortunately for your argument, there is no legal prohibition against him standing in front of her car.
Without that justification, her actions posed a credible, criminal, imminent, threat of death or grievous bodily harm, which justifies the use of any level of force, up to and including lethal force, to stop that threat.
You have not answered my question. Did the officer have a duty to retreat? If so, under what legal theory do you believe that duty arose?
This is an example of someone killed because of bad police training and decision making that ignored entirely how scary even normally benign police interactions can be to black women.
Scared or not, she had a legal duty to follow the officer’s lawful instructions. Scared or not, she had a legal duty to yield to a pedestrian in the path of her vehicle. Neither her race nor her sex nor her medical condition relieve her of those legal duties.
