On 2 December 2015, Syed Farook and Tashfeen Malik attacked a Christmas gathering in San Bernardino, California, killing 14 people and wounding 22. On 4 December, the news media were granted access to the couple’s home by the landlord. The ensuing news scrum entering the house was broadcast live to air, with reporters in the house identifying objects. In this paper, we use Membership Categorisation Analysis and particularly categorial inferencing to examine the way journalists, on being granted access to the house for the first time, and under pressure to produce news live on air, resorted to various forms of speculation and assumptions to generate news within the liminal zone. In particular, we examine how objects found in the home were used to occasion newsworthy discourses through categorial reasoning around why and how these objects were used and what they might indicate about the people and events. It is through these routine social categorial reasoning practices that it is possible to examine journalists’ routine work as displaying a “news-culture-in-action” whereby individuals and their actions are rendered as news relevant categories and articulated through categorial inferred reasoning practices.
