Kelvin Kong Hok-lai is the new head of the police's National Security Department, sworn in Tuesday by Chief Executive John Lee. He replaces Andrew Kan Kai-yan, who's gone on pre-retirement leave. Same day, police put out the line that Hong Kong still faces "soft resistance." No arrests attached to that one, no case number, just the phrase, floating there like it does every few months.

Look, I don't know what soft resistance looks like on a Tuesday in Sham Shui Po. Nobody selling fish balls has ever shown me any. But here's the pattern worth noticing: every time this job changes hands, the warning gets repeated, like a new manager reading the shop rules out loud on their first day. New chief, same script. Meanwhile the actual news happening at street level this week is a CCTV camera going up outside a shopping mall after a stabbing, and a mentally ill man sent to psychiatric care for it. That's the security story people are living with. The other one just needs an appointment letter.
