The fifth case study aims to further test the book’s central hypothesis by bringing two additional dimensions to our investigation. The first relates to group violence, extending our research beyond individual radical and hateful violent actions. The chapter argues that while restorative justice approaches focus on individual harm-doing and responsibility, their applicability to group offending and group accountability remains largely empirically unexplored. The second dimension relates to the localised implications, complexities, and specificities of violent radicalised action, especially when it comes to building resilience and implementing preventative strategies and programmes. The chapter zooms into the significance of localisation for prevention through the analysis of a small-scale, London project. Through volunteering and social action, the project generated new findings that tested the book’s positive approach. The two project target groups were local young people at risk of (or with experience in) group or radicalised violence, and professionals working in formal and informal settings to support them. The findings point out several caveats in the implementation of restorative justice and the RJiNEAR model, especially in the context of group violence.
