摘要：This article adapts Marshall McLuhan’s writings on mass media to ubiquitous and universal surveillance systems, looking at surveillance as media . The term ‘broadcast media’ is derived from an agricultural metaphor, a technique of planting. I argue that CCTV systems are an inversion of broadcasting: ‘harvest media’. Drawing on three case studies in which CCTV has been relevant to allegations of police misconduct, I explore how harvest media impacts on cultural and legal perceptions of evidence, truth and deniability.
