I was intrigued by this book because it is about an interesting topic, and because it is by a former police officer. I was very disappointed that I didn't get much out of the book. Unless you are a hermit and have never encountered human life, you know most of the things discussed in the book. There are a couple good topics, but overall it was lacking. As a Criminal Justice major, I found the interrogation tips decent, but felt there was much more to be discussed. I do not suggest this book unless you live all by yourself in the woods and want to know how human interaction works.
