They’ll probably conclude that he was a nut, give him an insanity defense, regret that community reports weren’t respected, and make at least some superficial adjustments.
That’s at least the beginning of a door to the sanity of keeping such things off of police forces.
I wonder if he deafened his partner by reaching forward and shooting right past his head three times. I wouldn’t be surprised if the partner has some significant hearing loss.
He reached over and shot multiple times through the door or window of the police car at an unarmed woman who had called 911 to report an assault. He should at least be fired, and probably should be charged with manslaughter. That’s my take on it from what we know right now. Inexcusable.
