Peace officers need to be "present" in the moment--each moment, and held to a higher standard of consciousness OJT where oops! isn't an acceptable defense. Yes, at that moment, one can be distracted both by fear and learned hatefulness.

Sooo...this one was educated, well-trained, and "not stupid" enough to say the wrong things...kinda worrisome it could come down to "distracted copping" or "distracted dressing" (in proper uniform by standard positioning of accessories), much like texting or other tasks while driving. Either task is wearing or controlling something that can easily kill for lack of conscious control. Would this person not tested the charge of a taser or failed to load her service revolver each day upon dressing in the uniform of her occupation??? Oops?

Tasers need to be of instantly recognizable bright color and worn at a location, perhaps cross-body, from the easier faster loaded and holstered favored handgun, though there would still be questions of judgment of which to use; of course, bodycams also recording each encounter!
