If you have not read Jeff Cooper’s work, Principles of Personal Defense, it is now available free online. It one of those works that every armed and unarmed person should read and know. A tip of the hat to Claude Werner for bringing to my attention the free online version now available. I have my original copy from the 90’s still on my shelf, and I have bought 2 more since for both of my girls. They both read it when they were 11 years old. While free is good, and information is information, I highly recommend buying your own copy and re-reading it every few years.
