Self defense is self defense. I fail to see how distance, the gun you use, who you are, etc, has anything to do with magically changing something that is justifiable, to something that is not justifiable. Im not saying that shooting at extended ranges is the best choice/option, but it "may be" your only choice/option, and if it is, then its no different than anything else. Self defense is self defense.The point is, you have to justify a shooting as self-defense at any distance and at some point, it isn't justifiable, unless you're a law officer.
Maybe, maybe not. Whos to say? Only the person in the spot, and in the second, really knows.None of this is to say you're in no danger from someone at a distance of 25 or 50 yards. It's just that opening fire is probably not your only option.
25 yards really isnt all that far away, nor is 50 yards for that matter. If you feel you have no other option, you shoot. Hopefully, youve practiced shooting what you have on you at those distances, and this isnt the first time.
