One of the world's foremost experts on crime reveals 7 tell-tale signs when someone is trying to con you

Before age 13, Gavin de Becker had suffered countless beatings, seen his younger sister subjected to the same abuse, and witnessed his heroin addicted mother shoot his father.

Instead of turning to violence himself as an adult, de Becker used his horrific childhood experiences to become one of the world's foremost experts on how to predict, and potentially prevent, violent, criminal activity.

Though he's written four books over the course of his successful career, de Becker is most famous for his first best-seller "The Gift of Fear," wherein he describes seven tell-tale signs to watch out for when someone is trying to control you.

Whether it's a con artist after your money or a violent criminal after something far worse, these signs are as true now as they were when de Becker first wrote them, and they can help you to identify a predator and protect yourself from becoming a victim.
