Laboratizing the border: The production, translation and anticipation of security technologies

This article critically interrogates how borders are produced by scientists, engineers and security experts in advance of the deployment of technical devices they develop. We trace how sovereign decisions are enacted as assemblages in the antecedent register of device development through the everyday decisions of scientists and engineers in the laboratory, the security experts they engage, and the material components of the device itself. Drawing on in-depth interviews, observations, and ethnographic research of the EUfunded Handhold project, we explore how assumptions about the way security technologies will and should perform at the border shape the development of a portable, integrated device to detect CBRNE threats at borders. In disaggregating the moments of sovereign decision-making across multiple sites and times, we question the supposed linearity of how science comes out of and feeds back into the world of border security. An interrogation of competing assumptions and understandings of security threats and needs, of competing logics of innovation and pragmatism, of the demands of differentiated temporalities in detection and identification, and of the presumed capacities, behaviours, and needs of phantasmic competitors and end-users reveals a complex, circulating and co-constitutive process of device development that laboratises the border itself.
