On August 23, 2020, a black man, Jacob Break, was shot from behind by a police officer in Wisconsin, USA, and was seriously injured, damaging his internal organs and spinal cord. Immediately after the incident, protests were held in various parts of the United States, and the next day, a Molotov cocktail was thrown into the headquarters of the police officers' union in Seattle, Washington.

From a document released on February 3, 2022, the FBI asked Google to disclose 'information on all Android devices that passed through the surrounding area before and after the Molotov cocktail was thrown.' It is clear that he used a 'warrant'. Geo-fence is a term that refers to an area surrounded by virtual boundaries, and it is possible to identify a person who has entered a certain geo-fence by using location information such as a smartphone.

In an affidavit, FBI agents said, 'Around 11:00 pm on August 24, 2020, two unspecified suspects used an object that appeared to be an instant ignition device to build the Seattle Police Officers' Union building. 'Intentionally caused damage.' 'Based on the above, we claim that there is a good reason to search for information currently held by Google or related to devices reported to be in the area covered.'

Was from 22:00 to 23:15 on August 24, 2020.

Google generally provides law enforcement with an anonymized list of Android devices that have passed the range specified in the Geofence Warrant, and one of these devices is involved in the case. Law enforcement agencies will be able to extract more detailed information if it becomes more likely. According to court records, Google also provided a list the day after the warrant was issued in an investigation into the attempted arson case at Seattle Police Officers' Union Headquarters.

Foreign media The Verge pointed out that the FBI issued a

$ 20,000 bounty for information on the incident in April 2021, a few months after issuing the Geo-fence warrant. The information on the Android device provided under the warrant did not lead to the arrest of the criminal.

A Google spokeswoman told The Verge, 'We have a rigorous process designed to protect user privacy while supporting the important work of law enforcement agencies.' Meanwhile, FBI and Seattle Police Department spokesmen did not respond to The Verge's request for comment.

The use of geo-fence warrants has increased rapidly in recent years, with Google receiving only 982 geo-fence warrants in 2018, compared to 11,554 in 2020, a more than 10-fold increase. ... apparently ...
