This course will investigate the origins, evolution, and modern usage of surveillance methods, technology, and forensic evidence in criminal legal systems. Using United Kingdom and United States examples and case studies, students will explore a variety of legal principles and frameworks for governing and regulating use of surveillance, technology, and forensic evidence in criminal cases. Particular attention will be given to the application of surveillance methods, technology, and forensic disciplines to marginalized communities, including communities of color and poor communities. Topics may include: (1) the origins of policing and surveillance; (2) the emergence of modern forensic disciplines; (3) the expansion of the surveillance state and modern uses of technology in criminal legal systems; (4) the impacts of law enforcement use of forensics, surveillance, and technology on communities; and (5) critiques and avenues for reform of use of surveillance, technology, and forensic evidence for criminal law purposes.
