This article examines what happens when a prevention strategy developed in one institutional setting is transferred into another. Using the Swedish implementation of Group Violence Intervention, particularly Sluta skjut in Malmö, it analyses focused deterrence as a mechanism package rather than merely as a policy label. The article argues that the effectiveness of focused deterrence depends on the coordinated reproduction of several linked conditions: credible identification of violence-producing groups, intelligible communication, believable consequences, inter-agency coordination, normative legitimacy, and practically available support or exit pathways. When the strategy travels across legal, organizational, and governance contexts, these mechanisms cannot be assumed to travel intact. On that basis, the article distinguishes among three explanations of weak or uneven preventive outcomes: strategy failure, implementation failure, processual misalignment produced through institutional translation. The Swedish case is used as an analytically strategic case rather than as a definitive test of focused deterrence. The central argument is that a transferred intervention may remain formally recognizable and be implemented with considerable seriousness while nonetheless losing part of the processual leverage on which its effectiveness originally depended. The article contributes a framework for analysing travelling prevention models, refines the concept of prevention misalignment, and develops a more process-sensitive interpretation of cross-contextual violence-prevention strategies. This article forms part of the Theorem-Driven Crime Process Research Programme and applies its processual framework of criminogenic exposure, social mediation, gated realization, and temporal persistence to the institutional translation of preventive interventions.
