How sad. Hoping for the daughter’s full recovery.
With that said, although I would be petrified if there was an unknown person in my house, really petrified, I would not want to shoot, without first lighting up the target to ensure that it isn’t some neighbor kid, or lost drunk. And in my neck of the woods those are the most likely scenarios. Not too many armed break-ins in these parts, thank goodness.
So for me, I’ve decided it’s better to take the added risk of clearly identifying my target, than to kill an innocent.
