The deadly attacks on a public meeting and on a Jewish citizen in Copenhagen in February 2015 have given rise to a vast amount of public discussion and interpretation of the events themselves, their background, their causes, their significance, and their repercussions. During these discussions, various conceptions of publicness and public space have been articulated. Indeed, one may view the killings as a ‘critical discourse moment’ in which a range of discourses have been employed to help interpret, understand, and deal with what happened. In several of these discourses, conceptions of publicness play a central part. This article sets out to investigate the conceptions of publicness that were articulated in the Danish public spheres following the attacks. The article maps out some of the key different and partly contradictory notions of publicness that the reactions to the killings brought to the fore. The investigation thus focuses on the articulation of normative expectations and ideals of public spheres, on the limitations and restrictions that were acknowledged, and on the main societal problems and (inter)national contexts to which publicness was viewed as related. The analysis will cover national newspapers and center on the discursive resources of the media elite in early responses to the attacks, for example in editorials, or comments by writers, academics, debaters, and intellectuals.
