Yes, if a crime is committed or such there is a reason. That over weighs other reason. But 99% of everyday situations aren't that.

Then there is the other side: some I dividuals have very good reason for not being tracked. Be it key witnesses to some major crime, somebody taking a clear side on israel-palastine-conflict. Etc. These are few, too, just like crime.

In the middle are the "normal" people. For them is maybe a potential minor nuisance if their spouse sees they weren't they assumed to be or when the boss sees them in a private outfit or something.

And then there is German culture, which did quite some research in how two different dictatorial regimes used surveillance and which effort they took and how innocent people got into Stasi files and into total surveillance.

And then we have the technology. Hiding cameras and mics is trivial these days. And cloud vendors doing facial recognition on all pictures uploaded (including faces far in the background - sometimes I am fascinated how well even my locally hosted immich works and identifies my brothers where I am not sure which one it was ... while it sometimes still fails) which makes that a tough balance.
