Is this a real email from the FBI?
Dear Google user,
Google has received a search warrant issued by the Federal Bureau of Investigation compelling Google to produce records related to Google accounts that have Location History data in a specified geographical region and date/time range. Google’s response to the warrant will include information about your account. The agency reference number or case number on the legal process is 3848298.
Unless we promptly receive a copy of a filed motion to quash that is file-stamped by a court of competent jurisdiction, Google may provide responsive documents (including information about your account) pursuant to applicable law, such as the Electronic Communications Privacy Act. See 18 U.S.C. § 2701 et seq. In most cases, the file-stamped motion to quash must be received by Google within 7 days of the date of this notification.
