It could be useful to protect people from relatiation under an authoritarian government, such as in Hong Kong. I dislike the idea of a government using mass automatic identification, that could be used again by authoritarians for terrible goals. I also dislike the idea of the opposite and using automatic anonymizing to protect criminals during riots. We're probably going to keep seeing an arms race in this, with good and bad actors on all sides.
Good. Black people factually live under an authoritarian regime in the US.
The problem in this case is that its institutionally racist towards, and extrajudicially assassinates, black people with impunity.
We must be more precise because otherwise it allows _this_ to happen.
