In a recent video, lawyer Jeff Hampton delved into the controversial use of cell site simulator technology by law enforcement. This technology, originally developed for military applications, has found its way into police departments across the United States. Here’s what he put together.
The Technology Behind Cell-Site Simulators

Cell site simulators, commonly known by brand names such as Stingray or Hailstorm, act as decoys that mimic legitimate cell towers. These devices trick nearby cell phones into connecting to them, allowing law enforcement to intercept and gather data from those phones. This includes text messages, call logs, and other personal information.
Find Wherever You Are

Hampton explained that whether you’re at home, in church, or at a bar, this technology can pinpoint your location down to the very room you’re in, as long as you have your cell phone with you.
The Scope of Surveillance

The videos shared that the troubling aspect of cell site simulators is their broad reach. Not only do they capture data from the target phone, but they also intercept information from any other phones within their range.
Justify the Use

Hampton shared that law enforcement agencies justify the use of this technology by claiming they are targeting specific individuals. However, the technology does not discriminate, capturing data from all nearby devices.
The Secrecy

Hampton highlighted the secrecy surrounding the use of these devices. “At least 75 agencies in 27 states have purchased this technology, and they’ve been using it for years,” he said. “Yet, they’re very tight-lipped about it and often sign non-disclosure agreements with manufacturers to keep details from the public.”
Legal and Privacy Implications

The video shared that the use of cell site simulators has sparked legal debates, particularly regarding the Fourth Amendment, which protects against unreasonable searches and seizures. Courts have struggled with these cases because of the lack of transparency about how the technology works.
The Case

Hampton shared the case of Andrews v. Baltimore City Police Department where it was revealed that the FBI and other agencies had entered into non-disclosure agreements to prevent discussing the technology, even in court.
Warrants and Misleading Practices

While obtaining a search warrant is often required for using such intrusive technology, law enforcement agencies have sometimes misled courts about the nature of the devices. Hampton shared that they have described Stingrays in court documents as pen register devices, which are much less invasive.
A Pen Register

He added that a pen register just records phone numbers dialed from a particular phone, whereas a Stingray forces phones to connect and gathers extensive data, including location information within a private residence.
The New Policies

The Justice Department has implemented policies requiring federal agents to obtain probable cause search warrants for Stingray use in criminal investigations. However, Hampton shared that these policies do not have the force of law and do not apply to state and local law enforcement unless they are working with federal agencies. Moreover, exceptions for national security and exigent circumstances further weaken these protections.
Calls for Legislative Action

To address these concerns, Hampton urged viewers to support the Cell Site Simulator Warrant Act of 2023, which is currently before Congress. This bill would require all law enforcement agencies, federal and local, to obtain a valid search warrant before using cell site simulator technology.
Beyond Government Surveillance

Hampton also touched on the issue of privacy in the digital age, noting that it’s not just the government but also private entities that invade our privacy. Scammers and marketers exploit our personal data, often obtained through data breaches or sold by companies.
