In late November, a California state court issued a final decision interpreting a 2015 California state law regulating government agency use of cell site simulators, devices that can be used to locate and track cell phones. The devices are commonly known as “stingrays.” The challenge—the first brought under this law—argued that the City of Vallejo was not in compliance with the law’s requirement that a local public body approve, at a public meeting, both police acquisition of the technology and a policy determining how and when these devices can be used. The court upheld this view of the law, providing an important victory for transparency.
Stingray devices present serious privacy risks because they allow law enforcement to track the physical location of anyone with a cell phone in real time. Originally billed as anti-terrorism tools, police often use them in routine investigations of nonviolent crimes. Furthermore, stingray devices can access data about all phones in an area, ranging from a few hundred yards to about 2 miles, even if the police are interested in only one device. Because of these “dragnet” capabilities, I and others have argued that localities should have the opportunity to decide if and how stingray and similar devices should be used in their communities. The California state law mandates this local decision-making process, providing an opportunity for needed transparency and democratic oversight.
The law was untested in court, allowing localities to interpret the law to their benefit, which, for city governments, often means the least resource-intensive view. Vallejo, for example, argued that as long as someone in the city government created a usage and privacy policy, it was in compliance with the law. The court’s ruling reaffirmed that a public decision-making process about when and how these devices are used is required by law.
