Surveillance: Laurie Taylor explores the way in which we have become the watchers, as well as the watched. From 9/11 to the Snowden leaks, stories about surveillance increasingly dominate the headlines. But surveillance is not only 'done to us' – it is something we do in everyday life. We submit to surveillance, believing we have nothing to hide. Or we try to protect our privacy. At the same time, we participate in surveillance in order to supervise children, monitor other road users, and safeguard our property. Social media allow us to keep tabs on others, as well as on ourselves. Laurie Taylor explores the contemporary culture of surveillance. He's joined by Kirstie Ball, Professor of Management at the University of St Andrews, and David Lyon, Professor in the Department of Sociology at Queen's University, Canada. Revised repeat.
