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.
This is not new and it has previously been used against anti-abortion activists, tracking locations and even being used to record religious confessions. People on both sides of the abortion issue can oppose this type of monitoring.
