This week, Insight delves inside the minds of the stalkers. Those accused of stalking tell Insight what they do and why they do it – some are remorseful; others aren’t. They are joined by guests who share their intensely personal and harrowing accounts of being stalked by former partners and aggrieved clients. Psychologists and police also weigh in to explore the definition of stalking, whether the laws are doing enough to protect victims, and whether stalkers can be reformed.
