Then why didn't she shoot him right off the bat? Why wait? And of the four officers on the scene why was she the only one who thought the suspect had to die?
That is patently untrue. He stopped his vehicle in the middle of the road. He was refusing or unable to comply with the officer's lawful commands. There was ample evidence he was under the influence of drugs, both from his behavior on the scene, and possibly reflected in his arrest record. We know now from his family that he was a PCP user.
Whether or not the officer should have shot him at that moment will be decided in court.
But the idea that Mr. Crutcher was "doing nothing wrong" and "a threat to nobody" is 100% straight-up BS.
I note again you argue in a duplicitous way, assuming and creating strawmen instead of addressing what was actually stated.
