This book was written 30 years ago and it reads like it. Many statements by the author come across to me now as stereotypes and assumptions. As a layperson, I would be interested to hear what today’s criminal experts think of this book. And, as the book was published before 9/11 and the opioid crisis, I would also be very interested to hear what the author’s thoughts on terrorism and drug addiction are today. Less useful as a writing reference and more interesting as a time capsule.
