The aim of this paper is to consider the relationship between an emergent decay of social trust created by the Covid-19 pandemic and the formation of “in” and “out” groups. Data from 37 extensive semi-structured interviews with members of the public in England found that identifying the “other” through normative conceptions of “security and order” was used by participants to legitimize their own presence within the “in” group, while self-reported compliance with restrictions was used to construct identities to be in line with that of the “in” group. These findings have important implications both for social trust within and between communities and toward the police.
