The question of whether law enforcement agencies can use Stingray cell-site simulators without individual warrants has become a critical civil liberties issue, particularly as agencies like the Las Vegas Metropolitan Police Department continue deploying these powerful surveillance tools. While a specific published lawsuit with that exact title could not be verified through multiple searches, the legal framework around Stingray use is clear: federal courts have established that warrants are required for this technology. In March 2016, Maryland’s Court of Special Appeals ruled in *Maryland v. Andrews* that law enforcement must obtain warrants before deploying Stingrays, resulting in evidence suppression in a murder case and setting a precedent that challenges the previously secretive and often warrantless deployment of these devices.
The core issue is straightforward: Stingray devices mimic cell phone towers and can sweep up signals from entire areas to track individuals, with some models capable of intercepting texts and calls. If used without warrants, they represent mass surveillance of innocent people. Understanding how these devices work, what the courts have said about them, and how to protect yourself if you suspect warrantless surveillance is essential information for anyone concerned about privacy rights in the digital age.

What Are Stingray Devices and How Do They Work?
Stingrays—officially called IMSI catchers or cell-site simulators—are sophisticated surveillance tools that law enforcement agencies use to track cell phones in real time. The technology works by mimicking legitimate cell phone towers, forcing nearby phones to connect to the device instead of to actual carriers. This allows police to identify, locate, and potentially intercept communications from specific targets or, in some cases, from everyone in a geographic area. The devices are manufactured by Harris Corporation and cost anywhere from $100,000 to $400,000, making them accessible primarily to larger law enforcement agencies with substantial budgets. The technology can do far more than simply locate a phone. Some Stingray models can intercept SMS text messages and even monitor phone calls.
This capability has made them attractive to law enforcement seeking to track suspects or gather evidence in criminal investigations. However, this same capability means that warrantless use of Stingrays essentially subjects everyone in a target area to potential surveillance and communication interception—not just the intended subject. When used in a densely populated area like Las Vegas, a single Stingray deployment could capture data from hundreds or thousands of innocent bystanders. What distinguishes Stingrays from other surveillance methods is their indiscriminate nature when deployed without careful limitations. A targeted GPS tracker requires a specific warrant for a specific person; a Stingray deployment, by contrast, inevitably sweeps up information about everyone nearby. This distinction has become central to warrant requirement arguments in courts across the country.
Federal Court Rulings and Warrant Requirements
The legal landscape shifted significantly in 2016 when Maryland’s Court of Special Appeals ruled in *Maryland v. Andrews* that a warrant is required before police can use Stingray devices. In that case, law enforcement had used a Stingray to locate a suspect in an alleged murder investigation without first obtaining a warrant. The court suppressed the evidence obtained through the warrantless surveillance, finding that the use violated the Fourth Amendment’s protection against unreasonable searches. This ruling became one of the first major appellate decisions explicitly requiring warrants for Stingray deployment. However, a critical limitation exists in this legal landscape: obtaining a warrant for Stingray use is often far easier than obtaining a warrant for traditional surveillance.
Some jurisdictions have allowed law enforcement to use applications that merely state they need to “locate” a cell phone, without the detailed probable cause and specificity that other warrants require. Additionally, the fbi has historically required local police agencies to sign strict nondisclosure agreements before purchasing Stingray technology, creating a transparency problem. These NDAs mean that the public and even judicial oversight have limited visibility into how often Stingrays are actually used, whether proper warrants are always obtained, and what happens to data collected during deployment. The warrant requirement established by *Maryland v. Andrews* and subsequent cases represents significant progress for privacy rights. But if a jurisdiction signs an NDA with the FBI that limits disclosure of Stingray use to courts and the public, the practical ability to challenge warrantless use becomes severely constrained. Defendants in criminal cases may not even know that a Stingray was used to locate them, making it impossible to challenge the legality of the evidence.
LVMPD’s Known Use of Stingray Technology
The Las Vegas Metropolitan Police Department is among dozens of large law enforcement agencies—including the New York Police Department, Los Angeles Police Department, and Chicago Police Department—that currently use Stingray cell-site simulators. According to available reporting, LVMPD maintains Stingray devices but the specific details of deployment, frequency of use, and internal protocols remain “closely guarded secrets,” consistent with broader law enforcement practice around this technology. In 2017, the Las Vegas Sun published an investigative piece titled “Does cellphone-sweeping ‘StingRay’ technology go too far?” which examined the use of this technology by local law enforcement.
The article highlighted concerns about the technology’s capabilities and the lack of public transparency around its deployment. Despite this reporting, LVMPD has not disclosed comprehensive data about how many times the devices have been used, under what circumstances, or whether warrants were obtained in each case. The combination of LVMPD’s acknowledged possession of Stingray technology and the broader secrecy surrounding its use creates a legitimate concern for Las Vegas residents about the potential for warrantless or inadequately warranted surveillance. Without public disclosure requirements and court-enforceable accountability mechanisms, there is no reliable way for the public to know whether their constitutional rights have been violated through Stingray deployment.
The Transparency Problem and FBI Nondisclosure Agreements
One of the most significant obstacles to accountability in Stingray litigation is the FBI’s practice of requiring local police agencies to sign nondisclosure agreements before they can purchase or use the technology. These NDAs restrict how much information law enforcement can share about Stingray capabilities, deployment practices, and even the fact that a Stingray was used in a particular case. The result is a veil of secrecy that prevents both judges and defendants from understanding how extensively Stingrays have been deployed and whether they were used legally. This secrecy has practical consequences for criminal defendants and civil rights advocates. A person arrested following a Stingray-assisted investigation might never learn that this technology was used to find them.
Without knowledge of the Stingray’s involvement, they cannot mount a legal challenge to the surveillance or move to suppress evidence obtained through the device. Judges similarly may be left in the dark about Stingray use, making it difficult to rule on Fourth Amendment questions. Criminal Legal News reported in 2018 that “law enforcement scrambles to hide Stingray use,” documenting how agencies across the country have fought to keep their Stingray programs secret from public scrutiny and judicial review. For residents of Las Vegas and surrounding areas, this opacity means there is no easy way to know whether you have been subject to Stingray surveillance or whether that surveillance complied with legal warrant requirements. The secrecy itself becomes a form of constitutional violation, preventing accountability for potential abuse.
How Stingray Cases Differ from Traditional Search and Seizure
Stingray cases present novel legal challenges that traditional Fourth Amendment doctrine does not easily address. A traditional wiretap or GPS tracker tracks a specific person based on a warrant that identifies that person and the probable cause to monitor them. A Stingray deployment, by contrast, necessarily involves collecting data from multiple people in order to locate one target. This “collateral damage” to innocent bystanders raises questions about whether a warrant specifically naming the target is even sufficient to justify the use of the device. Some jurisdictions have begun to require “minimization procedures” as a condition of Stingray warrants—limitations on how long the device can run, how much geographic area it can cover, and what happens to data collected from non-targets. However, these minimization standards are not uniform across the country.
A jurisdiction might allow a Stingray to run for hours over several city blocks, capturing cell phone data from thousands of people, with minimal restrictions on how the non-target data is stored or used. Without strict minimization procedures, a “warrant” for Stingray use may provide only minimal legal protection. Additionally, the use of Stingrays raises issues of “trespass” to cell phone communications. When a phone connects to a Stingray instead of a legitimate tower, the Stingray essentially interposes itself into the communication channel between the phone and the carrier. Some legal scholars argue this physical interposition—the Stingray acting as a false intermediary—should trigger heightened privacy protections. This argument has gained traction in recent years, though it remains contested.
What Evidence Obtained Through Warrantless Stingrays Can Mean for Your Case
If you were arrested or subject to investigation following surveillance that may have involved a Stingray, the legal implications depend on whether a warrant was obtained, whether you can prove warrantless use, and what jurisdiction you are in. In jurisdictions that follow the *Maryland v. Andrews* precedent, evidence obtained through warrantless Stingray use may be suppressed—meaning it cannot be used against you in criminal court. Suppression of evidence can be outcome-determinative if the Stingray location data was central to the case.
However, proving warrantless use is difficult if law enforcement has not disclosed that a Stingray was used at all. You may have grounds to file a motion in discovery requesting disclosure of whether a Stingray was used in your case. If law enforcement refuses to disclose or confirms Stingray use without a warrant, you should raise this immediately with your criminal defense attorney, as it could form the basis for suppressing key evidence. In civil rights contexts, warrantless Stingray use may also support claims for violations of your Fourth Amendment rights, potentially resulting in damages against the agency involved.
Future Outlook and Ongoing Legal Battles
The legal battle over Stingray use continues to evolve. Advocacy organizations like the Electronic Frontier Foundation and the ACLU have pushed for stronger regulations and greater transparency. Some states have begun requiring warrants for Stingray use by statute, making the requirement part of state law rather than relying solely on judicial interpretation of the Fourth Amendment.
Nevada has not yet enacted a comprehensive Stingray warrant statute, but the issue remains active in civil liberties advocacy circles nationally. The future trajectory likely involves increased pressure on law enforcement agencies to disclose their Stingray programs, stricter warrant requirements, and heightened minimization procedures to protect non-target data. As federal courts continue to grapple with the technology’s implications, the baseline legal protections for cell phone users may become stronger. For now, awareness of the technology and your rights regarding its use remains one of the most important tools available to protect your privacy.
