I really don’t care about the SOP because if I were to shoot someone murdering people and trying to murder myself I believe the those upholding the law will see a clearly justified shooting. Less guns in the hands of good people simply means more sitting ducks. I don’t want to be a sitting duck.
The deck is stacked against the self defense shooter in a big city. Once a person is in custody there is a lot more incentive to keep them there and justify the arrest than there is to let them go and set a "bad example" for other citizens. This is the perspective of the LEO's and prosecutors. In the eyes of a cynical street cop any citizen who shoots another citizen for any reason needs to be taken out, for the future safety of his fellow street cops.
The root cause is all the drug and gang shootings, where every one involved is a criminal. A gang banger defending himself against another gang banger may meet the purely technical definition of self defense, but the street cops don't see it that way. They see that every one who pulled a gun needs to be taken out, and that extends to every other kind of shooting incident.
