BALTIMORE (AP) — The Baltimore Police Department has an agreement with the U.S. government to withhold certain information about secretive cellphone surveillance technology from the public and even the courts, according to a confidential agreement obtained by The Associated Press. On Wednesday, the department disclosed it has used the technology thousands of times since 2007.
The agreement between the police department and the Federal Bureau of Investigation also encourages the authorities and local prosecutors to sometimes dismiss cases instead of divulging details about the equipment. That arrangement, which was agreed to several years ago, has led police to believe that they can withhold evidence in criminal trials or ignore subpoenas in cases in which the devices are used.
The technology, using devices called Hailstorm or Stingray, can sweep up basic cellphone data from a neighborhood by tricking phones in the area that it’s a cell tower and identifying unique subscriber numbers. That data is then transmitted to the police, allowing them to locate a phone without the user even making a call or sending a text message.
The Baltimore police entered into an agreement with the Justice Department in 2011, which calls for the department to withhold information about the device in “press releases, court documents, during judicial hearings or during other public forums and proceedings.” The agreement states that the department must seek FBI approval before sharing any details with other law enforcement agencies.
The agreement also makes clear that neither the police department nor prosecutors are permitted to divulge information about the surveillance technology in court, and warns that if either agency suspects that a prosecutor is planning to provide information about the device in open court, it must “notify the FBI in order to allow sufficient time for the FBI to intervene to protect the equipment/technology and information from disclosure and potential compromise.”
The FBI’s agreement also says the agency can request the Baltimore police, in conjunction with local prosecutors, to seek dismissal of a case rather than “allowing others to use or provide” information about Harris Corp.’s surveillance technology if it would “potentially or actually” compromise the equipment.
In practice, Baltimore police officers are interpreting the nondisclosure agreement as instructing them to withhold evidence from the court, and ignore subpoenas relating to the technology.
Emmanuel Cabreja, a detective with the department’s advanced technical team, testified Wednesday in a carjacking and robbery case. In that case, Cabreja’s team used a Hailstorm to locate a stolen cellphone inside a group home where defendant Nicholas West was living. A juvenile was also charged in the case.
He said the department has deployed Hailstorm and similar technology roughly 4,300 times since 2007. Personally, Cabreja said he’d used it between 600-800 times in the past two years.
“Does (the document) instruct you to withhold evidence from the state’s attorney and the circuit court of Baltimore city, even if upon order to produce?” defense attorney Joshua Insley asked Cabreja.
“Yes,” he said. Cabreja also said he ignored a subpoena he received Tuesday to bring the device with him to court.
Police across the country have largely been kept silent on how they use the devices. Because documents about Stingrays and Hailstorms are regularly censored in public records requests by citizens and journalists, it’s not entirely clear what information the devices could capture — such as the contents of phone conversations and text messages, what they routinely capture based on how they’re configured, or how often they might be used.
Cabreja on Wednesday said the Hailstorm can identify phones from a 360-degree antenna from about a city block away in distance. He said no data, or content, is captured in the process; however he said the device detects the unique identification numbers assigned to cellphones that have the same service provider as the targeted phone within that radius.
“Given what (Cabreja) said about the technology involved, and the way a Hailstorm device connects to and ‘registers’ non-targeted cellphones, it’s likely that thousands of people in Baltimore have been unknowingly impacted by police cellphone surveillance,” defense attorney James Johnston told The Associated Press. Johnston represented the juvenile defendant in Wednesday’s case.
The FBI declined to answer questions about the case late Wednesday.
This is not the first case to inspire a push-pull between prosecutors, defense attorneys and judges about revealing details of the Baltimore Police Department’s use of the clandestine technology.
Baltimore Circuit Judge Barry Williams presided over an earlier trial in which the police apparently used a surveillance device to collect evidence on a robbery suspect. At a November 2014 hearing, Williams lost his patience with a state prosecutor after a police technician wouldn’t answer defense attorney’s questions about the device — citing the FBI nondisclosure agreement.
“You don’t have a nondisclosure agreement with the court,” Williams told police Det. John Haley, part of the department’s advanced technical team. “Answer the question.”
The prosecutors instead withdrew the evidence, avoiding the contempt citation and questions about the equipment’s use.
Two months earlier, Williams threw out evidence in yet another criminal case involving cellphone tracking after a police sergeant said there were unspecified “homeland security” issues when asked why the suspect was stopped.
“If it goes into homeland security issues, then the phone doesn’t come in,” Williams said, telling the prosecutor: “You can’t just stop someone and not give me a reason.”
This week, officials in upstate New York released documents about their Stingray use after a state judge ordered them to do so.

Golden State Warriors Program Is Inspiring Next Generation of Female Engineers
Breaking down barriers and biases that deter young girls from pursuing STEAM subjects is essential for creating a level playing field and ensuring equal opportunities for all. By challenging stereotypes and promoting a culture of inclusivity and diversity in STEAM fields, experts believe young girls can be empowered to pursue their interests and aspirations without limitations confidently. Encouraging mentorship, providing access to resources, and celebrating girls’ achievements in STEAM are all crucial steps in creating a supportive environment that fosters success.

The Golden State Warriors and e-commerce giant Rakuten are joining forces to inspire the next generation of female engineers through Building STEAM Futures, part of The City Calls campaign.
Organizers say the initiative is founded on the idea that science, technology, engineering, arts, and mathematics (STEAM) are crucial fields for innovation and progress, and empowering young girls to pursue careers in these areas is more important than ever. Studies consistently show that girls are underrepresented in STEAM fields, resulting in a gender disparity that limits potential and hinders diversity.

On Saturday, March 8, International Women’s Day, the Warriors and Rakuten hosted 20 middle school girls from Girls Inc. of Alameda County at Chase Center’s Above the Rim for a hands-on bridge-building experience. The young girls from Girls, Inc. of Alameda County had an opportunity to design, build and test their own bridge prototypes and learn the fundamentals of bridge construction from the Engineering Alliance and the UC Berkeley Steel Bridge Team.
This STEAM experience for the girls followed the first session in January, where they took a behind-the-scenes tour of the Golden Gate Bridge, learning about its design and construction from industry experts. The City Calls campaign, tipped off with the unveiling the Warriors’ new bridge-themed City Edition jerseys and court design earlier this year.

Special to The Post
In a world where technology plays an increasingly central role in all aspects of life, the importance of Science, Technology, Engineering, and Math (STEM) education cannot be overstated. Recognizing the significance of STEM for the future, focusing on young women and girls is a critical step in achieving gender equality and empowering the next generation.
Self-eSTEM, an Oakland-based non-profit organization, was founded by Adamaka Ajaelo, an Oakland native who had a successful corporate career with several Bay Area technology and non-tech companies. Ajaelo boldly decided to step away from these companies to give 100% of her time and talent to the non-profit organization she started in 2014 in the belief that she can change the game in innovation and future STEM leaders.
Over the course of a decade, Ajaelo has provided futurist tech programming to more than 2,000 BIPOC women and girls. The organization has an Early STEM Immersion Program for ages 7-17, Emerging Leaders Workshops for ages 18-25 and volunteer network opportunities for ages 25 and up.
In January 2025, Self-eSTEM will launch digital and generative AI programming, which provides digital literacy and AI literacy training through an entrepreneurial project-based activity. This programming will be a hybrid (i.e. in-person and online). Additionally, thanks to a grant from Comcast, in spring 2025, the organization will have a co-ed series for middle and high school students.
While the organization’s programs center on innovation and technology, participants also gain other valuable skills critical for self-development as they prepare for a workforce future. “Self-eSTEM encourages young women to expand on teamwork, communication, creativity, and problem-solving skills. The organization allows young women to enter STEM careers and pathways,” said Trinity Taylor, a seventh-year innovator.
“Our journey over the last decade is a testament to the power of community and opportunity, and I couldn’t be more excited for what the future holds as we continue to break barriers and spark dreams,” said Ajaelo.
“By encouraging girls to explore STEM fields from a young age, we foster their intellectual growth and equip them with the tools needed to thrive in a competitive global economy,” Ajaelo says.
Empowering young girls through STEM education is also a key driver of innovation and progress. When young women and girls are encouraged to pursue careers in STEM, they bring unique perspectives and problem-solving approaches to the table, leading to more diverse and inclusive solutions. This diversity is crucial for driving creativity and pushing boundaries in scientific and technological advancements.
Self-eSTEM has fundraising opportunities year-round, but year-end giving is one of the most critical times to support the program. Visit www.selfestem.org to donate to the organization, as your generosity and support will propel programming support for today’s innovators.
