Recently, on the stone steps in front of the Philadelphia Museum of Art in Philadelphia, Pennsylvania, thousands of protesters lay down to imitate dead bodies. "Pretending to protest" lasted 8 minutes and 46 seconds, the same length of time Freud was kneeling and locking his throat. During the protest, the protesters collectively shouted "I can't breathe" (I can't breathe). (Editing Zhou Jing)
