Shortly afterward, Hai began to speak with three foreign reporters, asking if they were covering human rights issues. The woman immediately barked an order into a cellphone and more than 20 plainclothes police officers showed up in seconds, Hai said. Bystanders spoke up for Hai, who had explained the case about his mother’s land. Police tried to take away the sign that Hai’s son held, but the crowd shouted at them to leave his son alone, he said. Police called for backup at the north gate. Hai, protected by the presence of foreign cameras, walked to the south gate and climbed into a taxi with his son. His protest lasted less than 10 minutes.
