A lot depends on a jury.
There was a shooting in Portland, Oregon a few years ago. A small business in downtown Portland, I believe that it may have been in the Pearl district, was held up by an armed robber. The robber left and was pursued by a person from the business. The pursuer was armed with a .380 auto pistol and shot the fleeing robber. The robber died as a result of being shot. The DA's office let it go to a Grand Jury and they declined to indict, in effect saying it was a righteous shooting. I can't remember where it went from there, if a civil suit was filed,etc..
Shooting such as this, justified or not, may alter how criminals approach prospective victims. With more states enacting legal permits to carry, it could have a dampening effect on daylight, public robberies.
Probably be an improvement over a suggested course of action some years ago when it was suggested if a woman was facing being raped that she void her bladder and bowels....which seems to be a typical liberal reaction to facing a dangerous situation.
