Police Hide Use of Cell Phone Tracker From Courts Because Manufacturer Asked

By Nathan Freed Wessler, Staff Attorney, ACLU Speech, Privacy & Technology Project at 9:01am
It appears that at least one police department in Florida has failed to tell judges about its use of a cell phone tracking device because the department got the device on loan and promised the manufacturer to keep it all under wraps. But when police use invasive surveillance equipment to surreptitiously sweep up information about the locations and communications of large numbers of people, court oversight and public debate are essential. The devices, likely made by the Florida-based Harris Corporation, are called “stingrays,” and unfortunately this is not the first time the government has tried to hide their use.

Court Ruling Gives FBI Too Much Leeway on Surveillance Technology

Court Ruling Gives FBI Too Much Leeway on Surveillance Technology

By Linda Lye, Staff Attorney, ACLU of Northern California at 5:09pm

Today, a federal district judge in Arizona issued a very disappointing decision concerning the government’s obligations to be candid with courts about new technologies they are seeking a warrant to use.

The case involves Daniel Rigmaiden, who is being criminally prosecuted for an alleged electronic tax fraud scheme. The government used a surveillance device known as a stingray to locate Mr. Rigmaiden. A stingray operates by simulating a cell tower and tricking all wireless devices on the same network in the immediate vicinity to communicate with it, as though it were the carrier’s cell tower. In order to locate a suspect, a stingray scoops up information not only of the suspect, but all third parties on the same network in the area. This means that when the government uses a stingray to conduct a search, it is searching not only the suspect, but also tens or hundreds of third parties who have nothing to do with the matter. When the FBI sought court permission to use the device to locate Mr. Rigmaiden, it didn’t explain the full reach of stingrays to the court.

The ACLU and the Electronic Frontier Foundation filed an amicus brief arguing that when the government wants to use
