Many contemporary surveillance practices take place in information infrastructures which are from the public domain. Although they have far reaching consequences for both citizens and their rights, they are not always subject to regulatory demands and oversight. This being said, democratic fora where citizens and institutions may question such practices cannot be mobilised without widespread awareness of the dangers and consequences of surveillance practices and who is responsible for them. Through an analysis of surveillance controversies across Europe, this book not only examines the troublesome relationship between surveillance and democracy; but also highlights the vested interests which maintain the status quo. Using a participatory theory lens, Surveillance and Democracy in Europe reveals the historical, social, political and legal antecedents of the current state of affairs. Arguing that participation is a sensitising concept which enables a wide array of surveillance practices and processes to be interrogated, this insightful volume will appeal to students and researchers interested in fields such as public administration and policy, political studies, organisational behaviour and surveillance and privacy.
