Documents Reveal Anaheim, CA Has Surprisingly Robust Surveillance Arsenal For Small City

Anaheim Police have spent almost a decade secretly building an inventory of powerful cell phone surveillance devices and making them available to neighboring cities in Orange County, documents obtained by the ACLU of California reveal.

This cell phone spying program—which potentially affects the privacy of everyone from Orange County’s 3 million residents to the 16 million people who visit Disneyland every year—shows the dangers of allowing law enforcement to secretly acquire surveillance technology. The devices include the suitcase-sized “Stingray” equipment, another hand-held and easy-to-hide cell phone spy tool, and—most surprisingly—a military-grade piece of equipment known as a “dirtbox” that until now was only thought to be used by the federal government and two major cities.

If a city of only a few hundred thousand people like Anaheim has purchased this wide array of devices, it raises the question of how widespread these tools really are.

Additionally, Anaheim has claimed in its secretive funding requests that “every city in Orange County has benefited” from its cellular surveillance equipment, raising further concerns about transparency, democracy, and accountability. It’s bad enough that Anaheim’s secretive acquisition of this surveillance technology deprived the city’s residents of the opportunity to participate in critical decisions affecting their own community. But by loaning out this technology well outside Anaheim’s borders, the police department has subjected people all over Orange County to surveillance decisions made by unelected leaders from other communities.

A cell site simulator, often referred to as “Stingray,” mimics a cell tower and tricks nearby cell phones into communicating with it. In order to function, these devices interact with all cell phones in radio range, which means they potentially retain data about the communications and locations of innocent people.

Although federal, state and local governments widely use cell cite simulators, governments have gone to great lengths to hide information about how those simulators work and are used. Anaheim’s secrecy here is not an accident. The city and its departments bought these devices in secret and initially refused the ACLU’s request for public records. Only after we filed a public records lawsuit and engaged in extensive discussions did Anaheim produce any documents, which were heavily redacted—an on-going point of contention in our lawsuit.

What the documents show

Anaheim has possessed at least three different forms of cell phone surveillance technology since at least 2009, the documents show. The police department used a federal grant that year to purchase a dirtbox from a Maryland-based company named Digital Receiver Technology, Inc., or DRT. A dirtbox can collect information about thousands of phones at once, and a predecessor version of Anaheim’s device is capable of intercepting and recording digital voice data, according to a classified catalog recently leaked to the media. Other dirtbox models are capable of breaking the encryption of cellphone communications, according to media reports. One of the unique features of a dirtbox is that it can be airborne, and as a consequence scoop up information from not just a few hundred phones in its vicinity, but from thousands of phones. Until now, the only reported domestic use of these powerful devices was by the federal government and the cities of Los Angeles and Chicago.

In 2011, two years after buying the dirtbox, Anaheim appears to have bought a Stingray from Florida-based Harris Corp using a combination of federal grant dollars and local funds. And in 2013, Anaheim’s Chief of Police approved an upgrade to the department’s Stingray the ACLU believes enabled it to monitor modern LTE cellular networks.

Finally, in late 2013 Anaheim also purchased a controversial hand-held cell phone surveillance device manufactured by a company called KEYW and marketed as a tool for covertly locating phones and LTE signals in hard-to-reach places, including the interiors of buildings. The documents turned over to the ACLU, when compared with publicly available price quotes, strongly suggest that Anaheim bought a device called a Jugular. With a lightweight Jugular in hand, individual officers can easily conduct cell phone surveillance around and inside of buildings, including private homes, without alerting bystanders.

Potential warrantless use

The documents obtained in the public records suit do not confirm whether Anaheim police investigators obtain a warrant before using these devices. The records state that Anaheim obtains a “court order” or “court approval” for use of the DRT, KEYW, and Harris devices, but a court order is not necessarily based on probable cause, as is required for a warrant. This is important because devices like the KEYW Jugular can be used to find devices in hard-to-access spaces, such as the interiors of homes where people have the right to be secure from unreasonable searches under the Fourth Amendment.

The ACLU documents predate CalECPA, the new California law requiring a warrant for these devices. We do not know what legal process Anaheim seeks for cell phone surveillance today.

The ever-expanding use of these devices appears to go beyond Anaheim’s city limits. Anaheim represented in funding requests that it makes its cell surveillance arsenal available to other police departments in Orange County and had written procedures for sharing the dirtbox. The secretive use of this equipment outside of Anaheim means the police department not only deprived its own residents of the opportunity to debate or choose whether to be subjected to cell phone surveillance, it also did the same for the residents and elected leaders in neighboring jurisdictions, undermining the democratic process in those places as well.

It’s time for reform

Law enforcement entities should never acquire surveillance technology without telling the public, let alone multiple generations of devices capable of spying on private communications, as these Anaheim documents show has happened there.

Anaheim’s slide towards more and more surveillance illustrates the risks of secret surveillance outside of the democratic process. But communities are fighting back. As federal and state policymakers pass new restrictions on cell surveillance devices, local communities are moving forward with surveillance reforms that range from robust use policies for Stingrays to civilian oversight communities to an ordinance that requires transparency, accountability, and oversight for all surveillance technologies.

The ACLU is hopeful these reforms will take hold in places like Anaheim too so that when police seek the next generation of surveillance technologies, it won’t take the public seven years and a lawsuit to find out about it.

Machete murder occurred across the street and 7 or more San Diego police obtained this evil search warrant that has to be unconstitutional forced their way into my home and stole my video surveillance device and my usb drives, treated me like a 'JEWBOY' and treated the suspects and criminals like royalty.

hitler took my parents photographic privileges, several police and judges took my parents photographic privileges away in Los Angeles, the youtube 12 second video policethreat sd62010 show san diego police taking my photographic privileges away.


The entire premise of a "law & order" society is that the "ends do NOT justify the means" - we follow laws and follow the Constitution.

The U.S. Constitution and it's subordinate local, state and federal statutes [Article VI of the U.S. Constitution] is the due process or the "means" of reaching the "ends".

Today police chiefs, agency heads and other top management have reversed that premise - now the "ends" always justify unconstitutional or even illegal "means" - the U.S. Constitution is meaningless to these top managers. Rank & file police officers simply follow those illegal orders from their police management or are penalized by their own police departments and police unions. This type of police corruption is driven from the top down.


No matter what you do the police will not adhere to the rules unless its builtin and they can not circumvent it. Just like the Chicago police are destroying their on-body camera and mics... still dreaming that they will allow accountability when you allow them alternatives.


There is currently no federal agency with the teeth or integrity to criminally prosecute warrantless spying by local, state and federal police agencies.

There are numerous federal "color of law" statutes that already exist which could be used to prosecute warrantless spying.

The problem is the U.S. Department of Justice itself is actually involved in warrantless spying and they are also the same agency that enforces these "constitutional" statutes - statutes that define constitutional rights (what is a constitutional violation and the penalty if a police officer violates federal law). For example: Title 18 [criminal code] statutes 18 US Code 241-245 could also be used for the crime of warrantless spying or federal "pattern & practice" criminal statutes.

Any law, including the "supreme law of the land", is meaningless without risk of penalty for law breakers. If there is no real risk for the crime of warrantless spying, why would police chiefs stop doing it?


I have a list of the other cities involved. Huntington Beach, Buena Park. I can prove those.


I am going through the same thing as well. The persons involved are all connected by the common thread. I pay for a cell phone that isn't in my name and has no service. I am not allowed access to certain sites and the service provider can't be found. This provider doesn't recommend me changing anything. I have been provided a number to leave messages that's been put there along with apps I didn't have on my phone before. What do I need to do? I haven't been able to use my phone for over 3 years. I am sure that it is all about the money.
