Abstract
Biotechnology's promises has been widely recognized as a major enterprise accelerating the commodification of the biological. After the 9/11 events and the subsequent anthrax letters, biotechnologies have additionally been described as contributing to the construction of biosecurity risks. This paper proposes to investigate the collaboration between the FBI and the DIYbio network as a case study illustrating the productive entanglement of biological risks and promises. To do so, the paper explores the social construction of risks and promises associated with the vision of distributed biotechnologies as enacted in this collaboration. We argue that the FBI needs to police the DIYbio network in order to disseminate a specific notion of bioterrorist risk, while, in a counter-intuitive manner, the DIYbio network benefits from being policed by the FBI as it helps them disseminate their socio-technological vision. If the entanglement of technoscientific risks and promises is a well established finding of the STS literature, our case study suggests that such entanglement now additionally comprises the sphere of biosecurity and the promises of a distributed biotechnology available to everyone.
