Privacy advocates got access to Locate X, a phone tracking tool which multiple U.S. agencies have bought access to, and showed me and other journalists exactly what it was capable of. Tracking a phone from one state to another to an abortion clinic. Multiple places of worship. A school. Following a likely juror to a residence. And all of this tracking is possible without a warrant, and instead just a few clicks of a mouse.
It should be obvious to anyone who knows the first thing about how cell phones work.
Remember, you replied to me. You seemed quite proud of your comment and all your links. Unfortunately you completely missed the point.
