Paxton Quigley's book is a compliation of parts of other books on firearms self protection. It's a bit overdone, and probably would scare the average woman thinking about protecting herself. Women seem to have special problems protecting themselves. They usually do not want to hurt anyone, and they will do all most anything for a baby or a family member before they will do anything to protect themselves. However, women that are able to continue to practice with a hand gun, usually become quite proficent. They know that they don't know, and they listen to instructions. Most men think they know it all already.

This book by Vincent Bugliosi is by far the best book I have ever read. The Manson murders being the most interesting subject I have ever researched. Being the prosector in the longest trial in American history the author is also an extremly good writer! I recommend this book to anyone and it is well worth the money
