As a concealed carrying card holder the thought of having to shoot any individual causes me concern. That being said, if I have to use deadly force to respond to deadly force to protect myself, my family or others who are in danger then I will do so. Shooting to kill an individual is not in my vocabulary, I will shoot to stop the threat. If I happen to kill the bad guy then that is the breaks. I am a good shot, but I am not good enough to shoot a knife, gun or deadly weapon out of the bad guys hands. I am not going to try to shoot him in the arm or leg to stop him. He is probably moving and I might miss and hurt someone else. I was trained to shoot center mass and shoot until you stop any assailants. If during that time I kill the bad guy, then I stopped the threat. If I did not kill the individual, should I render first aid to him? The answer to that is a definite NO. That individual did his best to maim, mutilate or kill me or my family. If I did not kill him, he may be playing possum waiting for me to get close enough for him to try again. First, consider your own protection, are there other assailants, move to cover and concealment, reload your firearm if possible. Second, call 9-1-1, get police and medical help. Third, call an Attorney. If EMS/Paramedics arrive first, you can be sure they will not treat or assist the bad guy until law enforcement arrive and secure the area. When PD arrives, holster your weapon, give a brief statement of the facts, then plead the 5th until you talk with your attorney.
