Abstract
Most offenders, even persistent offenders, eventually desist from crime, and the fastest period of deceleration in the frequency of offending is in the early twenties. This article summarises results from a longitudinal study of desistance from or persistence in crime in this age range, illustrated by three case histories. A key finding is that, because of their deep prior engagement in crime, would-be desisters from repeat offending need to make many adjustments to their patterns of daily life. The authors explain why virtue ethics has been found to be a valuable resource in theorising these results.
