If I have to kick, punch, or otherwise strike, you can be sure it will be one of the optimal and terribly sensitive parts of the body. And should I have the time, I would love nothing more than to put a bullet in a tender part of someone's non-vital anatomy, if for no other reason than to stop and savor the look on his face. However, I have a feeling that most self-defense situations that would involve me firing my weapon will not involve me having the time or foresight to carefully aim.
Our prime purpose in this life is to help others. And if you can't help them, at least don't hurt them.--The Dalai Lama
