Query: Excellent book for anyone working with the public

I noticed the reviewers highly recommend this book for law enforcement personnel and I agree it is probably very useful for them, but I also think this book is helpful to a much wider audience. As a school counselor, I have applied the principles in this book in many situations with students and parents which might have escalated into dangerous confrontations. I believe anyone working with the public could benefit from Mr. Thompson's ideas.
