The Iranian government first arrested Kianoosh Sanjari when he was a teenager protesting a crackdown on student activists. He remained undeterred. For two decades, the regime repeatedly threw him into jail and detained him in psychiatric institutions, but the more Iran tried to silence him, the more outspoken Sanjari became. Last Wednesday, Sanjari plummeted from a commercial building in Tehran, hours after declaring that he would take his own life as a final act of protest if the government did not release four political prisoners by the evening. He was 42.
