In 2019, one way or another, you’re being tracked. Bail bondsmen and prison sheriffs can buy data in bulk and exploit software to gain real-time location data of anyone nearby. Governments can conduct sting operations in conjunction with cellphone makers to break encryption keys or set up fake cell towers to harvest information, known as “stingrays” or “IMSI catchers.”
