Back in March, as it investigated a spate of armed robberies across Portland, Maine, the FBI made an astonishing, unprecedented request of Google. The feds wanted the tech giant to find all users of its services who’d been within the vicinity of at least two of nine of those robberies. They limited the search to within 30-minute timeframes around when the crimes were committed. But the request covered a total space of 45 hectares and could’ve included anyone with an Android or iPhone using Google’s tools, not just the suspect.
The FBI then demanded a lot of personal information on affected users, including their full names and addresses, as well as their Google account activity. The feds also wanted all affected users’ historical locations. According to court records, while Google didn’t provide the information, the cops still found their suspect in the end.
