We're joined on this week's episode of The Explainer by Dr Paola Rivetti, an associate professor in politics and international relations at DCU whose research interests focus on the government of societies and polities in the Middle East and on social and political mobilisations, to examine what exactly has happened since Mahsa Amini's death on 16 September. What exactly is driving so many people out in protest, who are the morality police, and is there anything different about these demonstrations compared to what we've seen before in Iran?The Explainer is brought to you by The Journal.
