If I got my gun out on a rape call, how is that malice? I would call that prudent police work...but not in the car.
I agree his was mishandling his gun. Not what I would do or have done, even on shots fired calls.
No law that I am aware of that states there is a minimum or maximum times you can shoot someone...
Please produce a cop training manual that requires the cop to hold the gun in his lap, finger on trigger, shoot unarmed civilian attempting to report a possible crime, multiple shots towards victim.
No victim gun found on scene!
A civilian would most likely be toast and the trial and deliberation over in one day.
Also investigate if her civil rights were violated.
