Jurisprudence changes VERY slowly, and for good reasons. But I believe there is movement in a good direction about location data privacy.
For a long time, the thinking was, there is no expectation of privacy in public so your location in public is not 4A protected. That was kinda reasonable 50 years ago, before massive scale data aggregation. In recent years the courts are slowly recognizing that indescriminate aggregation of loc history creates a difference in kind. The “entirety of your movements” should enjoy 4A protection, even tho a single observation of your loc is not protected.
The courts are not a monolith. There are hundreds of thousands of judges each with their own views. The system changes slowly. There are judges still adhering to the “no expectation of privacy in public” idea. But there is a shift happening. Even SCOTUS has started to recognize that dragnet loc surveilence is a problem.








I believe you are right.
Which cuts to something else. I do not think most ppl have an intuition, for just how little info is sufficient to ID them. It isn’t much! That unfortuntely, makes life hard for we who value privacy. And easy for those who attack privacy.
Mathematically it isn’t an impossible fight for us. But it is an up hill fight.
