To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is a really disappointing book. It is comprised of anecdotes...about 150 pages worth, then a commentary and a few other appendices as fillers. The authors may have had very successful and impressive careers but there is so little of substance in the book and it is worthless to anyone wanting to learn. For example: a whole chapter is devoted to an imaginary interview with OJ Simpson...de facto this chapter is nothing more than fiction. I guess it is included because the authors had nothing to say! Which in my humble opinion sums up the book.
the techniques are entry level intimidation techniques. They aren't affective but are still used by weak detectives in poorly managed departments. If you're hoping to shutdown and interview just dip a toe into any of these methods.
The book was quite badly damaged. Clearly a very poor quality factory second. Quite disappointing really. No stars for this effort. Actually I’m forced to give a star to enable submission of this review. Hopeless.
