As to not derail this LEO oriented thread, a quote from it;
Though the circumstances will differ for a civilian, the questions still remains - at what point does one make the decision to use deadly force?
In my mind - and the way I've tried to program my mind - is that all aspects of AOJP must be satisfied. Ability, Opportunity and Jeopardy should all be fairly easy to ascertain in an encounter, but it's the Preclusion aspect that IMO requires the most thought and judgement at the time, and thus where there is potential for a freeze.
I believe the justifiable use of deadly force is a much more narrow band for a civilian than for a LEO. But at some point after the A, O and J have been satisfied, I can envision getting stuck in the same kind of loop being discussed in the linked thread: has everything reasonable been done to avoid using deadly force?
For a civilian, is any verbal engagement such as taught by SouthNarc ("that's close enough", "don't make me shoot", etc.) required to satisfy preclusion? Once a potential assailant is engaged verbally, where does the line get drawn to avoid "getting stuck in the loop" and perhaps seriously injured or killed as a result of it?
Great discussion in the linked thread, I hope creating a new one here with a "civilian CCW spin" makes sense.
