In PRC, because of cultural differences I think most people accept the crime safety net you get over personal freedom restrictions and you can't really meaningfully challenge any such move even if you wanted to. Anyway, it is the same in Singapore and people seem happy with it despite being exposed to all the Western culture too, so I think it is a cultural thing.

The thing that British were the first to roll out this but we haven't seen any advanced analysis stuff out in public after it kind of shows the apprehensiveness around it.
