'What are you in for?' The neglected role of the offence in prison sociology.

Why have prison scholars so seldom discussed what people in prison think about their crimes? This article addresses a striking gap: the omission of the originating reason for incarceration - the offence - from sociological analyses of carceral life. We examine its past treatment in prison scholarship and argue for recentring it. Drawing on three case studies, we show how the offence actively shapes daily experience, institutional engagement, and social dynamics. Our framework explores how attention to the offence can illuminate what prisons are like, what they do through moral communication, and what they are for as sites of punishment. Our analysis suggests that attending to the offence can enrich our understanding of adaptation, compliance, and legitimacy, and more generally add to our understanding of imprisonment.
