Not to doubt you or anything, but I question why you have no doubt in your mind. Are you trained to use a gun? Have you pulled the trigger on something that wasn't a human being? To be fair, I haven't. I am trained on how to hold a firearm and even the various ways to slice someone up and beat them to death, but as it stands I have yet to do so. However, because of my training, I understand the responsibilities of doing these actions in the first place. In all honesty, I would probably do this on the battlefield or, while I doubt it will happen like this, on the streets if my life is in potential danger. I usually carry non-lethal, but effective, weapons, such as a pair of kubatons, a trainer kerambit, and an expandable baton for sever cases.
