This week, Kathleen tells us about the science behind stalking. What is illegal stalking, and how is it different from ‘courting’ behavior? What motivates stalkers? What is the impact of stalking on the victim? And who among the Mind on Crime ladies stalked a celebrity as a teenager? Then Erin tells us about a stalking case that led to legal changes to the psychology profession, and Natalie tells us about one of the first ever cyberstalking cases.
