Does CCTV displace crime?

Abstract

Crime displacement is a concern often raised regarding situational crime prevention measures. A national evaluation of closed circuit television cameras (CCTV) has provided an interesting test-bed for displacement research. A number of methods have been used to investigate displacement, in particular visualization techniques making use of geographical information systems (GIS) have been introduced to the identification of spatial displacement. Results concur with current literature in that spatial displacement of crime does occur, but it was only detected infrequently. Spatial displacement is found not to occur uniformly across offence type or space, notably the most evident spatial displacement was actually found to be occurring within target areas themselves. GIS and spatial analysis have been shown to complement more typical crime analysis methods and bring a much needed dimension to the investigation of displacement.
