I get why human rights orgs would want to speak against this technology, from a Western philosophy and law perspective. China does not have the same philosophical or legal lineage. They will have to find out on their own whether the cons outweigh the pros. Theoretically, if the system is not corrupted by misinformation (false or incomplete information), it has the potential to keep the streets free of wanted criminal…
Just like you, I believe we will achieve this some day. The problem is that if the system is corrupt - and it very much looks like it is, anywhere in the world, not just in China - these tools allow that corrupt system to live on, without correction.
Technology has long passed the advance of society and individual human minds, and that is a major problem, for which I have no solution for - nobody does.
Please let society catch up, let basic income become reality (essentially let us not worry about lowest level of the Maslow Pyramid), and only after that have this level of control. There is an incredible difference between a thief who steals food because of hunger, and someone who steals from banks for the thrill and fun, but this level of tech will only be useful on the first, who'd instead deserve help.
