Actually, I hate to admit it, but he had a point. When I was a firearms instructor, I would point out to the students that a firearm is not a defensive object. The mere possesion of one will not keep you safe. It is the willingness to use it in a timely, effective, and offensive manner that will. The object was to get them to come to terms with the aftermath of having to use it, and decide beforehand exactly what would be worth killing for. I did not teach them to shoot to wound.
