This article sets out the professional opinions of criminal justice practitioners on what works for the rehabilitation and reintegration of sexual and violent offenders. This primary study utilises a qualitative method informed through ten semi-structured interviews with practitioners in the field of rehabilitation and reintegration. The findings foreground barriers that hinder and aid the rehabilitation and reintegration of SAVO such as, doxing, social media vigilantism, and the impact of it. As a result, the findings build on current understandings of the barriers facing individuals who have committed such offences, and what practitioners would deem to be a positive social change in the development of rehabilitation and reintegration initiatives.
