ABSTRACT
This chapter explores publicly visible counter-terrorism measures–uncovering the strategic role of design in creating controlled disruption in public spaces to reduce threat while at the same time reducing anxiety. Martin et al. apply the urban planning concept of 'triangulation' to describe the use, in counter-terrorism strategies, of disruption of civil inattention as a means of assisting in informal surveillance and reporting. Publicly visible counter-terrorism interventions are often intended to evoke performances from people in a space. The chapter describes how the disruption techniques that underpin interventions outlined in counter-terrorism guidelines can be categorised as effecting triangulation of attention, unexpected performance or shifts in crowd flow. Design as disruption is intended to complement existing counter-terrorism strategies. Designing for Security: Using Art and Design to Improve Security illustrates how art might be integrated into New York City's security strategy: Artists and designers should not hesitate to use aesthetic tools as part of the arsenal of security.
