HONG KONG (NYTIMES) - Hong Kong has suffered through months of political protests. Its economy is shrinking. Mistrust divides its people from its leaders. Locals and expatriates alike already talk openly about leaving.

Airlines are cutting service, isolating an international city from the rest of the world. Schools are closed. Panicked residents are hoarding rice, face masks and - in the latest run - toilet paper.
