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.
I am aware that a number of african americans have been unjustly killed by police. That is a different claim than african americans are systematically oppressed by the US government.
For instance, compare what is happening in the US to a real authoritarian regime such as the USSR. The government made millions of innocent civilians disappear into the gulags en masse. Try to imagine even the hint of due process, let alone rioting and protests, within that regime.
Or compare what is happening here vs what is happening in China. The CCP places millions of Uighurs into concentration camps for no reason. In the US, we have thousands rioting violently in the streets, and I suspect the majority of the rioters will see little to no consequences for their actions.
