As cities across Iran erupted in another round of nationwide protest against the Islamic Republic, a young man named Reza Otadi joined his neighbors on the streets of Karaj, northwest of Tehran. They shouted “Death to the dictator!” and “Clerics get lost!” Shortly thereafter, Reza was identified by the regime’s domestic-security apparatus. On the evening of Aug. 3, as he made his way home, regime security forces shot and killed him. He was 26.
