For the first time, law enforcement accounting for just 4% of all geofence warrants served on the technology giant. the number of geofences warrants it’s historically received from U.S. authorities, providing a into how frequently these controversial warrants are issued. The figures, published Thursday, has received thousands of geofence warrants each quarter since 2018 and, at times, accounted for about one-quarter of all U.S. warrants that Google gets. The data shows that most geofence warrants are obtained by local and state authorities, with federal
According to the data, Google received 982 geofence warrants in 2018, 8,396 in 2019, and 11,554 in 2020. But the figures only provide a glimpse into the volume of contracts received and do not break down how often iton overly broad requests. A spokesperson for Google would not comment on the record.
Albert Fox Cahn, executive director of the Surveillance Technology Oversight Project (STOP), which led efforts by dozens of civil rightsfor releasing these numbers, commended Google for releasing the numbers. “Geofence warrants are unconstitutionally broad and invasive, and we look forward to the day they are outlawed completely,” said Cahn.
Geofence warrants are also known as “reverse-location” warrants since they seek to identify people of interest who were in the near vicinity when a crime was committed. Police do this by asking a court to, which stores vast amounts of location data to drive its advertising business, to turn over details of who was in a geographic area, such as a radius of a few hundred feet at a certain point in time, to help identify potential suspects.
these figures, partly because geofence warrants are primarily considered unique to Google. Law enforcement has long known that on its users in a database called Sensorvault, first revealed by The New York Times in 2019.
Sensorvault is said to have the detailed location data on “at least hundreds of millions of devices worldwide,” collected from users’ phones when they use an Android device with location data switched on orand Google Photo and even Google search results. In 2018, the Associated Press reported that Google could still collect users’ locations even when their location history is “paused.”
But critics have argued that geofence warrants are unconstitutional because the authorities compel Google to turn over data on everyone else in the same geographic area. Worse, these warrants have been known to trap entirely innocent people. TechCrunch reported earlier this year that Minneapolis police used a geofence warrant to identify individuals accused of sparking violence in the wake of the police killing of last year.
One person on the ground filming and documenting the protests had his locationby police for being close to the violence. NBC News reported how one Gainesville, Fla. resident whose information was given by Google to a burglary could prove his innocence thanks to an app on his phone that tracked his fitness activity.
Although the courts have yet to deliberate widely on the legality of geofence warrants, some states are drafting laws toagainst geofence warrants. Last year, New York lawmakers proposed a bill that would that police could use these warrants to target protesters — as happened in Minneapolis. Cahn, who helped introduce the New York bill , said the newly released data will “help spur lawmakers to outlaw the technology.” “Let’s be clear, the number of geofence warrants should be zero,” he said.
