IMO, and IME, if an individual intends to carry, or own a gun as a defensive tool, they must accept the responsibility that goes with that decision. The last thing any honest law abiding citizen should want to do is take the life of another human being. But if a person makes the decision to carry lethal force for the purpose of self defense, than they need to come to terms with that choice, in that it means you may have to shoot someone to defend your own life, or that of a loved one.
I have been in at least two situations in which the attacker played on my intentions, and even stated, "you won't use it", or "you don't have it in you to shoot ". In those situations the attacker read me wrong.
Either accept the responsibility, or don't. But don't carry one if you have no intention of ever using it should the need present. She was shot with her own firearm because she didn't accept that responsibility.Sitting on the fence is dangerous, and not just for that single victim, but all others the attacker should pick as their next victim, as he is now equipped with your firearm.
The other side of this coin is preparation and training. I've had a perpetrator attempt to take my weapon from me, in which I almost lost it. The distance a person can cover in a split second is surprisingly much greater than what most consider. My inability to effectively deploy and aim the weapon quick enough, resulted in me missing my mark with the first shot. Fortunately, or more so luckily for me, the first shot distracted the attacker just long enough for me to take proper aim, so that when he attempted to grab it the second time, I hit my mark. In my defense, he was dodging back and forth to try and get to me without getting shot, which almost worked for him, but ultimately he failed.
