The issue led to a public dispute three weeks ago in Silicon Valley, where a sheriff asked county officials to spend $502,000 on the technology. The Santa Clara County sheriff, Laurie Smith, said the technology allowed for locating cellphones â€” belonging to, say, terrorists or a missing person. But when asked for details, she offered no technical specifications and acknowledged she had not seen a product demonstration.
Buying the technology, she said, required the signing of a nondisclosure agreement.
â€œSo, just to be clear,â€ Joe Simitian, a county supervisor, said, â€œwe are being asked to spend $500,000 of taxpayersâ€™ money and $42,000 a year thereafter for a product for the name brand which we are not sure of, a product we have not seen, a demonstration we donâ€™t have, and we have a nondisclosure requirement as a precondition. You want us to vote and spend money,â€ he continued, but â€œyou canâ€™t tell us more about it.â€
The technology goes by various names, including StingRay, KingFish or, generically, cell site simulator. It is a rectangular device, small enough to fit into a suitcase, that intercepts a cellphone signal by acting like a cellphone tower.
The technology can also capture texts, calls, emails and other data, and prosecutors have received court approval to use it for such purposes.
Cell site simulators are catching on while law enforcement officials are adding other digital tools, like video cameras, license-plate readers, drones, programs that scan billions of phone records and gunshot detection sensors. Some of those tools have invited resistance from municipalities and legislators on privacy grounds.
The nondisclosure agreements for the cell site simulators are overseen by the Federal Bureau of Investigation and typically involve the Harris Corporation, a multibillion-dollar defense contractor and a maker of the technology. What has opponents particularly concerned about StingRay is that the technology, unlike other phone surveillance methods, can also scan all the cellphones in the area where it is being used, not just the target phone.
Wired Magazine named Harris Corporation the number 2 most dangerous thing on the internet right now.
The Harris Corporation and the U.S. Marshals Service are tied for going above and beyond to conceal information from the public, courts and defendants about law enforcementâ€™s use of so-called stingray technology. Harris is the leading maker of stingrays for law enforcement, which simulate a cell tower to trick mobile phones and other devices into connecting to them and revealing their location. Federal and local law enforcement agencies around the county have been using the devices for yearsâ€”in some cases bypassing courts altogether to use them without a warrant or deceiving judges about what theyâ€™re using to collect the location information. Why? They say itâ€™s because Harrisâ€™s contract includes an NDA that prohibits customers from telling anyone, including judges, about their use of the technology. Itâ€™s hard to know whoâ€™s really initiating the secrecy, thoughâ€”Harris, because it wants to protect its proprietary secrets from competitors, or law enforcement agencies, because theyâ€™re worried suspects will find ways to counteract the devices. The secrecy reached an extreme level this year when agents with the U.S. Marshals Service in Florida swooped in to seize public records about the use of stingrays to keep them out of the hands of the ACLU.
