Please be VERY careful how you phrase things. As responsible firearm carriers, our goal is to stop the threat. We make the decision to shoot in our self-defense realizing that our shots may kill, but our goal is always to stop the threat, not to kill.
If we draw and the attacker stops attacking or turns and runs away, do not shoot. Ensure you’re safe (check your surroundings and/or leave the immediate area to a safe location), and call the police to report what happened. Be the first to call the police.
