What does that have to do with national security? Public order =/= national security. National security is HK having one of the largest US consulates in the world because it was widely recognized as the western intelligence hub into PRC (a consulate that directly reports strait to US state department lol), no small part due to lack of NSL. That's what HK was, a national security state of exception for treason, one that PRC waited 20 years to close. Cue significant consulate downsizing after PRC pushed through NSL. Beijing cares about national security for the 1C part, not some public order minutiae like grandma getting shanked in 2S.

Also who cares? HK drowning in stagnant end stage capitalism is exactly the kind of optics PRC wants right now. What is side effect? HK youths flooding to mainland for a good time. Also see recent online discussions around residential fires, many HKers recognizing, valid or not that HK, like rest of west, is farcical procedure shithole that can't get shit done, explicitly highlighting mainland tier1 cities urban management has better execution vs hk having "better" paper laws. They see benefit of actual authoritarianism, just like RoW including disenfranchised in west in the last couple years. They don't want retarded paper order and muh rule of law that hasn't worked for them before or after NSL, because PRC still light kid gloves on HK, increasingly they want to get shit done, like a proper tier1 city.
