Review title: Not worth the cost
Product review: I decided to buy this book as I'm always looking for something about this matter, as I'm a self defence instructor for policemen, and I find this book really ... empty ! It has NO ONE idea to how really survive in this world, also: following to this book, we should always carry a bowie knife, a long heavy stick, a gun and some other hitting weapon with us. Great defense isn't it ? And a nuclear shelter where to live in? It's even not worth the cost
