I had this encounter at a gathering in November with an acquaintance. She was pro-government and said how it's the government that's helped everyone. She claimed the protesters are being trained by foreigners (maybe to fight?) down somewhere... Maybe Wan Chai. It was all very vague but it was the first time I heard any such thing and it was shocking to hear.
She lives in the HK equivalent of a castle in an affluent area up on a hill. Definitely a reliable source if information about how the average Hong Konger is learning how to "riot" from foreign influences, and probably a similar source to those informing our elite governing bodies.
