In theory: I am eating in a restaurant which is being robbed. Perp turns back to me still waiving their gun. I put six rounds into them. They drop. I walk towards the perp to kick their weapon away, maybe get patron’s wallets so I can hand them back. Adrenaline is still pumping. I see his arm move near the pistol, my immediate reaction while standing near the perp and seeing the hand with gun start to move might be to add one more round in an area I am certain will end the threat. Again, all theory. I feel for the civilian.
