I think this illustrates that people only worry about this kind of thing if it gets shoved into their face.
The privacy thing is OK as long as it’s only used for the good. For example, I think nobody would object against a world where every killer would be caught within an hour to get a fair trial.
However, such a world also would be one where every traffic offense could be fined, and where powers that be could find some dirt on anybody in their email history, presence on on-street cameras, etc. Worse, it would take relatively few people to pull that of.
That’s something I think nobody wants, but it’s abstract until it affects you, so few people worry about it.
Privacy absolution is never what most people signed up for.
Also, “the police” are thousands of humans. That makes it harder to use the police for oppression than if “the police” were a bunch of computers and robots.
If somebody proposed the latter, I think lots of people would object.
