This article focuses on situational crime prevention, a security policy which involves the shaping of space to reduce the likelihood of crime. Specifically, it focuses on the uses of situational crime prevention in two railway stations and two shopping centers. Different situational crime prevention devices (CCTV, lighting and layout of these spaces, access and flows management) are analyzed using qualitative data. I show how these devices reveal an implicit theory of disorder, how the logic of security is inseparable from business logic, and how producing order cannot be reduced to shaping space.
