An example of not so clear thinking
Say its 3 am and one has been asleep for an hour or two then hears something break or someone stumbling around in their house.All lights are off and there had been rumors of people running around doing all kinds of bad things in the neighborhood recently.What are you going to do?
Keep in mind you have no clue if the person is armed or not with no lights on.Do you cut the light on or start asking questions to give away your location,never know this person could be armed and a better trained shot than even yourself.This situation should not be judged by anyone with so few facts given,none of us were there and the article wasnt very informitive.
Absolute understand that. he must have been a very good shot to shoot him with no lights on and manage to kill him outright, someone who is very well trained i would imagine, but not trained enough to evaluate the situation, someone scared and yes, panicked. to tell the truth, I would panic too at that time in the morning if an intruder broke into my house, whether I could compose myself to be able to aim a gun and shoot him dead without saying anything first is another story.
But as you say, not enough info, so i will take it that the home owner got woken up at 3am from his sleep, got up and got his gun and shot the intruder dead in the dark with out trying to scare him off or even just shooting at his leg.
