Security as controversy: Reassembling security at Amsterdam Airport

Critical approaches to security have come to define themselves against mainstream security studies by not a priori assuming what security is, but rather taking it as an essentially contested concept'. Yet, as evidenced by the way in which recent turns' in the field have played out in the debate around airport security, ontological assumptions about security tend to restrict the scope of empirical analysis, with airport security being studied as, for instance, either discourse or practice. This article aims to propose an alternative methodological approach to security by studying security as controversy. Studying security as controversy means refraining from making a priori assumptions about the ontology of (in)security, instead considering it as itself at stake in - and hence the outcome of - security governance efforts. The article elaborates on this approach by drawing on core insights from actor-network theory, a conceptual and methodological toolkit that allows, as I show, a focus on how security actors perform security by enrolling, assembling and translating heterogeneous elements into stable assemblages that can be presented as definitive security solutions or threats. The article illustrates this approach through a look at the case of airport security at Amsterdam Airport in the aftermath of the 2009 Christmas terrorist attempt.
