How pervasive is vigilante violence in democratic Indonesia? What drives the phenomenon, and how does the state respond when citizens turn to vigilantism? Dr Dave McRae explores these questions and more with Sana Jaffrey in the final Talking Indonesia episode for 2017.

After leading massive protests against former Jakarta Governor Basuki ‘Ahok’ Tjahaja Purnama, the past few months have seen the Islamic Defenders Front (FPI) doggedly pursuing individuals who have criticised the organisation online. Sana Jaffrey and Siswo Mulartono look at the significance of this phenomenon and explain why is it likely to continue.
