You may not like this becuase it doesn't fit your little world view, but millions of people defend themselves each year with guns. This is a recent example of a mom who saved herself and her children from god knows what - with a gun.
While the woman and her children were definitely in a situation where they would feel threatened there was no mention in the article that the intruder intended to do them bodily harm. Cornered in the attic? I doubt he was hunting them down, remember he had checked the house several times, both by knocking and ringing the bell, to make sure nobody was home. He was robbing them and when he opened the attic closet he was immediately shot. If the intruder had had a weapon or in some way was threatening bodily harm then you can be sure that the digitaljournal (what is digital about guns?) would have included it and probably close to the top as it would have been much more sensational and brought in more readers / clicks. "Cornered" seems to be the best they could get away with but is obviously biased. It's quite the anti-climax to a sensational story, in the end the intruder was sentenced only to burglary. At least you admit that nobody seems to know know what she saved themselves from, "god knows what."
