This paper explores the roles that the presumption of innocence (PoI) can play beyond the criminal trial, in other dealings that citizens may have with the criminal law and its officials. It grounds the PoI in a wider notion of the civic trust that citizens owe each other, and that the state owes its citizens: by attending to the roles that citizens may find themselves playing in relation to the criminal law (such roles as suspect, defendant, convicted offender and ‘ex-offender’), we can see both how a PoI protects us, beyond the confines of the trial, against various kinds of coercion, and how that PoI is modified or qualified as we acquire certain roles. To develop and illustrate this argument, I pay particular attention to the roles of defendant (both during the trial and while awaiting trial) and of ‘ex-offender,’ and to the duties that such roles bring with them.
