This article critically examines the prospects of restorative justice in Brussels from the perspective of urban youth work. The insights issue from action research on the topic of ‘radicalisation’. The authors develop two arguments. The first tempers restorative optimism. It shows how restorative interventions are not necessarily the most adequate response to tensions and conflicts in urban settings. The second argument points out that resistance from urban youth workers regarding the implementation of restorative interventions should not be seen as a regrettable obstacle for academics who are eager to experiment with these interventions. Such a resistance can lead to new insights and fresh opportunities to radically rethink Restorative Justice. One of the ideas that the article brings to the surface comes down to this. In a city like Brussels, characterised by superdiversity, and clearly marked by social inequalities, academic researchers only gain credibility in initiating restorative interventions if they undeniably denounce these inequalities and fully express their engagement for social justice.
