"This is where mass surveillance comes in. While it is unreasonable to assume that everything you do in public will be kept private from prying eyes, there is a real expectation that when you travel throughout town over the course of a day—running errands, seeing a doctor, going to or from work, attending a protest—that the entirety of your movements is not being precisely tracked, stored by a single entity, and freely shared with the government."

"Historically, we have not expected the government to secretly catalogue and monitor all of our movements over time, even when we travel in public. Allowing the government to access cell site location information contravenes that expectation. The court stressed that these accumulated records reveal not only a person’s particular public movements, but also their “familial, political, professional, religious, and sexual associations.”"
