Excellent @stayoutoftherz! Thank you for providing me this link. I believe I have been exposed to some of this before, in various safety trainings. Some go one step beyond, by training you how to instantly respond in such a way as to reverse the element of surprise.
Hopefully, most of us will never need to experience how to do that, but sadly we live in times when to not have at least the right mindset is not wise. The Americans are often maligned and misunderstood about their Second Amendment rights. For trying to enlighten those people, I do not know how one would improve on the straightforward quote you have here from Jeff Cooper! 🤝
