Urban Surveillance, Safety and the Right to the City: A Theoretical Analysis of AI-Enabled Policing Infrastructure, Public Space and Civic Freedom

Abstract

Cameras, facial recognition, licence-plate readers and predictive policing analytics are being installed in African cities as safe-city infrastructure, often financed and supplied through foreign partnerships, in response to real problems of crime and insecurity. This theoretical paper analyses urban surveillance as an infrastructure of public space. Drawing on urban theory including the right to the city, on surveillance studies, on criminological evidence on the effects of camera surveillance on crime, and on recent research on smart-policing and safe-city deployments in Africa, it distinguishes three effects of surveillance infrastructure, on safety (whether crime falls), on behaviour (how people use public space) and on power (who can watch whom), and argues that the evidence for the first is narrower than claimed, the second is systematically underestimated, and the third is the effect that persists after the technology's crime-fighting value is exhausted. The paper develops a framework in which the legitimacy of urban surveillance depends on effectiveness, proportionality, accountability and the preservation of anonymous public presence, derives seven propositions about the conditions under which surveillance improves safety without eroding civic freedom, and examines the governance problems created when the infrastructure is vendor-controlled and the data leaves the jurisdiction. Nigeria's safe-city and security-technology initiatives, with Lagos as the anchoring case, ground the analysis. The paper closes with implications for city and state governments, regulators, vendors and the research agenda of African urban studies. It concludes that the right to the city in the age of the camera is the right to be in public without being known, and that a surveillance infrastructure which preserved that right while reducing the crimes that threaten it would be a genuine contribution to urban safety, whereas one that does not is a contribution to something else.
