I once testified in court as the firearm instructor of the cop involved in a fatal shooting. When asked if I taught the officers to shoot to kill or shoot to wound, I replied that I taught the officers to shoot the offender until he quit doing whatever it was that made the officer shoot him in the first place. Might have been the long way around, but it emphasized that it was the "other guy", not the officer, that caused the "other guy" to get shot.
