The flip side of having more guns in homes to allow people to protect themselves is that sometimes what should be routine turns into something fatal.
There's research in the book "Blink" by Malcolm Gladwell that found a similar thing, that, ironically, the move to pair police officers on the street to keep them safe actually increases the likelihood they will take aggressive actions which force them to use deadly force. When they were alone, they actually slowed down and took a more defensive posture to wait on back up. That often gave them time to consider all options, which tended to de-escalate tense situations.
But when they had a buddy with them, that defensive posture went away. Yes, because they felt safer, they reasoned, even without doing it on purpose, that they could push harder and faster.
That's why some researchers are saying that "stand your ground" laws are associated with an increase in homicides and killings. Did the same thing happen to that Georgia homeowner?
(Oh, I don't use "Latino" in the headline because I try to stay away from such labels unless it is germane to the story, and I don't see anything in that story that this has anything to do with race.)
