I have tried to explain to many people that this is actually the danger that comes with too many options. However, before we get to the options, due to the number of laws and their ever changing interpretations, officers spend most of their training time dealing with how to avoid legal missteps that attorneys will use to get the worst of the worst off. They typically only practice weapon use as it pertains to their qualification requirements.
Back to options hanging on their belts. Look at what the average officer carries on their duty belt. A firearm, a Taser, spare magazines, spare Taser cartridges, chemical spray, a baton, handcuffs, radio, PPE, ...
Now think back to our animal response to Fight or Flight:
Color vision goes away - Bright yellow means nothing
Gross motor skills go away - So much for touch and feel
Peripheral vision narrows - Tunnel vision and point and shoot - See target, but hands with weapon is out of view
Survival reflex takes over - What simulated practice does this situation relate to the closest
The events:
Good stop
Found more than expecting
Wright chose poorly to fight and flee
Use of force justified, but ... Oooooops! Wrong tool pulled.
Officer, daughter, wife, mother ... Life ruined. Now we wait to see what the judge will plan for her future.
