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.
I’ll admit I didn’t open the article, as far as I’m aware the best way to sidestep silly requirements like warrants is to just purchase data intended for advertising. Databrokers really have an amazing wealth of info ready to be tapped into, all you gotta do is pay.
