We’re Asking the Ninth Circuit to Hold Reverse Location Warrants Categorically Unconstitutional

The EFF and the ACLU have filed an amicus brief asking the US Ninth Circuit to hold reverse location warrants categorically unconstitutional, the EFF says. The warrants, known as tower dumps, require cellular providers to turn over location data about every phone in a given area at a given time, and the case, United States v. Spurlock, is the first of its kind heard by a federal appeals court since a US Supreme Court ruling on the issue.
