From The Verge:
Geofence warrants, also known as reverse-location warrants, allow authorities to sweep up location data from GPS, Bluetooth, and wi-fi from devices near a crime scene. They often pull in information from people who had nothing to do with the crime, and have raised privacy concerns. A Florida man who used a fitness app to track his bike rides briefly found himself a suspect in a 2019 burglary, when police used a geofence warrant. The man had unknowingly provided information about his location to Google, which placed him near the scene of the crime.
Warrants of this nature will hopefully be made illegal in the next hundred years.
