Crime Signals

How to Spot a Criminal Before You Become a Victim

David Givens, Ph.D.

St. Martin's Griffin

Crime Signals helps you stop crime before it starts. David Givens, one of the nation’s foremost experts in nonverbal communication, offers a fascinating and instructive look at crime, and into the tell-tale signs that give away all offenders—if you’re trained to see them. 

            From the signals of a swindler to the warning signs that experts use to help thwart terrorism and violent crime, this book breaks down a criminal’s body language into clear recognizable symbols:


• What does it mean if an assailant’s face turns suddenly pale?

• Is a pat on the arm from a salesman a sign of sincerity, or an indication that you’re about to get scammed?

• Does a liar make fewer hand gestures while they’re lying—or more?

• If an aggressor shrugs his shoulders, should you be afraid?


This is the first book to offer a comprehensive guide to the body language of criminals.  With amazing stories and instructive steps, it will change the way you view the world.


Praise for Crime Signals

“An exceptional text for reading criminal behavior.  Incorporating the latest research in nonverbal behavior, psychology, neurology, physiology, and the social sciences, David Givens simplifies the complex and marries it up with actual cases from today’s headlines. This book is not just for law enforcement officers, it is for anyone who is concerned about their own safety and the safety of their loved ones. This is a must read.” –Joe Navarro, FBI Special Agent (ret.), author of What Every Body is Saying.

“An essential tool for warding off crime, filled with fascinating real-life stories of crime and survival.” —Tuscon Citizen

“CRIME SIGNALS offers a comprehensive interpretation of nonverbal body language. By giving the reader an anthropological, biological, social, and psychological, perspective of body language, David Givens offers readers insight into the behaviors of criminal personalities.  If we are alert to the signals of criminal intent, we can better protect ourselves and the ones we love.” –Leigh Baker, author of Protecting Your Children from Sexual Predators.

“CRIME SIGNALS gives the reader valuable insights into human behavior and, most importantly, cues to criminal behavior that can help you from becoming a victim.” –Chief Alan Lanning, La Mesa Police Department

“This savvy, street-smart field guide to the many ways the hands, eyes, jaws, shoulders, and sweat glands of criminals betray what they’re about to do and what they have done is a must-read.  Find out why you should worry, for example, if you see men entering an airport in single file, or if you see people standing like statues within a convenience store.” –Connie Fletcher, author of Crime Scene: Inside the World of the Real CSIs

“Sorting the truth from lies and trying to understanding the criminal mind is a frustrating and elusive goal, but in CRIME SIGNALS David Givens takes us one step closer with a useful and fascinating overview of the movement, voice, and body language of those who do us harm.” –Gary M. Lavergne, author of Sniper in the Tower: The Charles Whitman Murders
