Let's say you are in the parking lot and a bad guy assaults you. Because you had your flashlight/pepperspray in your hand you are successful in blinding/disorienting him for a moment, and you konk him on the head or knee him in the kidney or swipe the knee. He's down, and you're out of there. You call it in, of course, to prevent his accusing you of assaulting him. You give the report, but they can't find him.
Now what? I would be a bit concerned about the fellow being upset with you and looking for revenge. Or his pals might be, especially if this were a successful shoot instead of nonlethal.
Do you conduct your life as you usually do and return to that store as needed? Do you avoid that store? That section of town? That town? If so, for how long? What does into your decision-making?
