The way privacy norms and abstract rules about limiting power come about is *not" through gradualism. It's through hurdled events. The american revolution. The 1989 revolutions. Particular points in time where you can say "Stazi bad. Never again."
The reality is that these chouces involve compromising security. Slightly freer, and slightly less safe is not a winning political argument.
Imagine a system where detectives can plug it back a name or a face and retrieve location information from that person's phone, city-wide CCTV video, etc.
Creeoy, but more crimes will be solved.
Gradualism favours security over freedom in the long term. There are 19 rapists walking free in our city today, because limits on police power.... There's only one way this argument goes.
