This paper isolates the causal effect of policing on group violence, using unique panel data on self-reported crime by soccer and ice hockey hooligans. The problem of reverse causality from violence to policing is solved by two drastic reallocations of the Stockholm Sport Intelligence and Tactical Unit to other activities following the 9/11 terrorist attack in September 2001 and the Tsunami catastrophe in December 2004. Difference-in-difference analysis reveals that Stockholm-related hooligan violence increased dramatically during these periods.
