He left a wife and children. Moral? Do not go outside if you do not have to.
That's one of the hazards.
One of the others is that the police, who are responding to either your wife's call or a neighbor's (who may have seen or heard the BG first), may encounter you outside with your gun in hand before they find the BG. A sudden meeting like that in the dark can easily have tragic consequences for all involved, and this has happened repeatedly in the past.
In a city or suburban environment, you are in the best position to safely and effectively protect yourself and yours while leaving the bad guy with all of the tactical downsides when you stay inside, take a good defensive position, and let the police handle whatever is outside.
There is no upside in going looking for him or them in a low light, 360 degree threat environment and exposing the most effective potential defender to being easily neutralized (read "shot and killed") by a hardened street thug who will know enough to keep still and wait until you present a target he can't miss.
