FCC Needs to Impose Strong Protections Around Stingray Use

For years, state and local police departments across the country have been using Stingrays to track and locate phones in the absence of effective oversight from federal agencies. That may soon end. Today, the ACLU and ACLU affiliates in Northern California, New York, and Maryland, joined by the Electronic Frontier Foundation, are urging the Federal Communications Commission to order local police to stop using Stingrays, at least until the FCC can create rules to protect against excessive secrecy and abuse.

Stingrays, also known as cell site simulators, track phones by mimicking cell towers and tricking phones in the area into broadcasting their unique identifying information. In the course of communicating with those phones, Stingrays can interfere with their ability to make and receive calls. Last month, three civil rights groups—the Center for Media Justice, Color of Change, and New America’s Open Technology Institute—filed a complaint with the FCC pointing out that state and local law enforcement agencies are violating the Federal Communications Act by using Stingrays without the required FCC broadcast licenses and in a way that interferes with cellular communications. Focusing on the staggeringly frequent use of Stingrays by the Baltimore Police Department, the complaint also pointed out their disparate impact on communities of color.

Our submission to the FCC supports these arguments, and provides the FCC with additional information about the widespread use of Stingrays by dozens of law enforcement agencies across the country and the ways in which police have intentionally hidden information about the technology from local lawmakers, judges, and the public. As we tell the FCC, any system for providing Stingray use licenses to police departments “must be predicated on strong protections to minimize interference with cellular communications, to facilitate proper oversight from local elected lawmakers and from courts, and to ensure transparency to the public.”

Before local police should be allowed to use a Stingray, they should be required to obtain explicit approval from the local elected legislative body (like the city council) after fully disclosing the impact of Stingrays on bystanders’ cellular communications and privacy, and allowing for public debate. The communities affected by surveillance technologies need to be intimately involved in deciding if and how they should be used. The FCC should also require that police departments:

  • disclose information about how Stingrays work and their impacts on third parties to judges before obtaining warrants;
  • comply with federal Department of Justice guidelines for Stingray use and adopt additional procedures to minimize the impact on bystanders’ communications; and
  • publicly report information about acquisition and use of the technology.

Only through strict oversight and transparency rules can we hope to curb illegal and discriminatory uses of surveillance technology. Many of the state and local police departments that use Stingrays have a documented history of racial bias in their policing activities, making it incredibly important that local communities have sufficient information to decide whether and how police should be permitted to engage in invasive surveillance.

Lack of a mostly publicly-funded election campaigns is a big part of the problem.

If members of Congress and state legislatures received most of their funding from citizens, the laws would be focused on serving their constituents more than their campaign contributors.


Without a judicial warrant, it would seem to clearly violate federal statutes and think it's actually a felony crime to block phone signals.

Why not just arrest the police chiefs (not order-takers) for violating federal law? The big question is if FCC police can arrest FBI agents violating federal law using Sting Rays?


A stingray device was used on me after I made accusations regarding county level misappropriations. Every one of my contacts was bullied, my ex-wife given all details of all traffic on my phone. Critical emails and texts are either delivered late or never delivered at all. Editing of text and emails took place. While this was happening, I made a complaint to the county in question (a county I didn't live in). The members of the court concluded that no such technology exists to perform these actions.
I discovered this abuse by installing tower monitoring software via F-droid on my android, and could see my connection change, at times, to a mobile, unregistered cell tower.
Subsequently, this county moved a closed divorce case from another county to theirs. The records are suppressed so I cannot view the details. They reopened our divorce case, immediately removed all things awarded by judgment in the other county. Removed custody of my child. Told my neighbors that I was dangerous, or that I was sexually deviant, or that I was on drugs - a variety of horrible things.
I have hope in reading this article because during this time any entities I contacted regarding this simply denied that the technology existed. On the notion that the technology did not exist, it was ordered that I undergo a psychological evaluation. I did so.
However, the court refused to accept the (negative) results of the examination, and then countered that I had to see their doctor that works in their county. When I contacted this person (bear in mind, I had been obeying the court's demands the entire time), they advised me that they would do a new psychological evaluation. When I asked them if they would need a release for my medical records, the doctor responded, "No, that won't be necessary. We're going to start fresh without someone else's opinion".
Coming to find that standard medical diagnostic protocol prescribes for evaluation of medical history as part of the process, I felt already that there were intentions regarding any diagnosis.
Now I see on this website, the talk of regulating Stringray usage - whereas the denial of their existence to begin with was the basis for which this county felt justified in ruining my life


I simply could not leave your web site before suggesting that I really enjoyed the standard info an individual supply for your visitors? Is gonna be again steadily to inspect new posts.
