The violence of FPI will be explained by the social movement perspective especially with the vigilantism and framing concepts. Framing will explain about the source of legitimation towards the violence. Meanwhile, the vigilantism will explain about the pattern and behavior in the act of violence. One conclusion that can be drawn is FPI act of violence in Yogyakarta is not always related with the religious issues, but also began with their hostility with Front Jihad Islam/FJI.
