I found this to be a very good read and also wish I had a book or manual like this years ago when I first got into law enforcement. This would have been very useful back in the early 80’s when I started and when I left 30 years later some or a few of the principles were making their way into that field. One example is the author goes through the process of making the correct decision when under stress. I had to learn this first by actually being in stressful situations that could injure my partners or myself. I had to learn from older more experience people and through just by being in stressful situation, now know problem, but back then a pause well? Here the author shows you some ways. This book though is good for any business and also helpful in team building and how to get everything out of all the people working for you. Finding the right way to task some people as opposed to others would be very helpful if you are operating your company. I came from a military father so some of what he saying I had already heard, but what was good about this book was different way of saying the same thing my father said but not from a man who fought in WWII and Korea, both said the same but used different words. Like I said I think many people especially in the law enforcement field that I left, could use some of the items he talks about. Some are also very good tools for your own life as well. I really enjoyed this book.
