Abstract

Recent decades have seen an unprecedented proliferation of surveillance programs by government agencies. This development has been driven both by technological progress, which has made large scale surveillance operations relatively cheap and easy, and by the threat of terrorism, organized crime and pandemics, which supplies a ready justification for surveillance. For a long time, mass surveillance programs have been associated with autocratic regimes, most notoriously with the German Democratic Republic and the Stasi, its secret police. A more recent case in point is the efforts of the People’s Republic of China to set up a comprehensive surveillance system that assigns citizens a score reflecting their social and political conformity. But the current rise of state mass surveillance is mostly attributable to the new readiness of liberal democracies to monitor their populations. The vast surveillance system uncovered by whistleblower Edward Snowden is maintained and supported by a group of established liberal democracies, including the United States, the United Kingdom, Canada, and many others. While surveillance programs of authoritarian regimes, installed to monitor and quash political dissidents, are uncontroversially unjust, surveillance operations carried out by liberal democracies possess at least some prima facie legitimacy. They are set up with the stated objective of protecting citizens against terrorism, organized crime and pandemics, which few would deny is the duty of any state. Still, the expansion of large-scale surveillance by democratic governments has widely been perceived as objectionable or at least problematic on account of its harmful effects on both individuals and liberal society at large.
