Authorities say a man opened fire on a suspected burglar who attacked his wife at their home
Deputies said [the intruder] encountered a 74-year-old woman inside the residence and ‘began to struggle with her physically.’ Her husband heard her screams and saw her struggling with Jackson. The man then retrieved his firearm and shot Jackson in the right shoulder.
This is what I call a ‘downrange incident.’ I.e., there’s an innocent party downrange and in close proximity to the attacker. Incidents where close range precision is required are more common than is realized.
A downrange drill is part of all my private sessions above the beginner level. The shooter has only one round in the pistol. Two IDPA targets downrange with one placed directly to the side of the -0 zone. The shooter can advance to any distance they feel they can make a -0 hit, either head or body, on the first shot without hitting the hostage. Even experienced shooters tend to get somewhere within Social Space (4-12 feet).
It doesn’t have to be an IDPA match scenario
but practicing the ‘downrange shot’ occasionally is worthwhile.

Funny story. Many years ago now I was teaching my student Jeeyun to shoot. GP100 3” with .38 Spl. range ammo. She could keep her shots on a paper plate at 5 or 7 yd., I forget which. So I set up a hostage target, with a printed photo of me as the hostage and the head and shoulders of the bad guy showing. I told her to shoot to save the hostage. She told me she couldn’t because “ I might hit you.” I said no, that’s just a picture and I’m right behind you. “Oh,” she said, and made the shot successfully. Five or seven yd. I was proud of her.
I periodically think of your experience with her. The psychology of shooting is frequently more important than the mechanical aspects.
After our conversations on this subject, and seeing what happens in FoF, and in a few real life scenarios, I incorporate this sort of thing into my close quarters pistol class, and my LE weapon retention classes.
In my home invasion fight, I closed distance, punched my pistol into the offenders mouth, then down his throat, fired a shot, ending the fight. His accomplices fled, abandoning their guns and get away car. Point being, firing your pistol from inside the antagonist is a shot that can’t miss. Practice that. Deadly Force is an intimate thing. Live it, when necessary.
