If you ask one person if owning a gun has saved their life, then you only get their own random experience. If you ask 1000 people, then you get a picture that is closer to reality.
Can you explain how you use your gun? Do you keep it loaded, on your bedside table at night? Do you carry it to the mall? Would you carry it if you were dropping a child off at school? Or are you just keeping it locked in the safe in case of a UN raid?
