Constructing the Suspicious: Data Production, Circulation, and Interpretation by DHS Fusion Centers

Suspicious activity reports (SARs) are an increasingly important tool in the law-enforcement repertoire, especially for counterterrorism. In spite of significant problems with such reports, they are experiencing a resurgence that can be attributed partly to the institutionalization of Department of Homeland Security (DHS) “fusion centers,” which are taking the lead in vetting and interpreting these reports as they enter into law-enforcement and counterterrorism databases. Based on a 3-year study of DHS fusion centers, this article reviews a range of problems with SARs and argues that robust community relationships are necessary to achieve contextually situated reports that eschew overt forms of bias.
