What was Barney Fife’s finger doing on the trigger, with no targets present, in the first place?
The cop that shot her needs to go to jail. The remaining cops in that department need a LOT more training, starting with “DON’T TOUCH THE EFFIN’ TRIGGER UNTIL YOU HAVE A TARGET AND ARE READY TO SHOOT!”
Yep a lot of firearm rules were not followed. Thus the results as reported. You can have a weapon drawn and even in a pre aim ready to shoot holding posture. But keep the finger off the trigger so you don’t accidentally shot someone nor yourself.
