Have you ever thought you were being followed or watched? Have you ever needed to follow or observe someone and not be seen?

In the world of espionage, surveillance and surveillance detection are a way of life. It is the job of every CIA operations officer to make sure he or she is not under surveillance—that is, being followed to the commission of an “operational act.” It is also the job of every CIA operations officer to surveil his own targets, whether they are terrorists or terrorist suspects, foreign intelligence officers, hostile actors, or even sometimes his own agents for vetting purposes.

In everyday life, many people from all walks of life need to know how to perform similar operations. Whether avoiding a stalker, checking up on an unfaithful partner, or just securing one’s own privacy, a working knowledge of modern surveillance and surveillance detection techniques is a critical skill to possess. And there is nobody better to teach that skill than someone trained by the CIA.
