For our September+October issue, we investigated the Border Patrol’s sharp growth, its troubling record on civil liberties, its culture of impunity, and its role in shaping the current political moment—one that echoes the anti-immigrant fever that led to the agency’s creation a century ago. Read the whole package here.
It was dawn and we were in Sunland Park, New Mexico, a few hundred feet from the border, watching the US government surveillance towers that watch all of us. They were positioned atop a bald hillside, taking in a constant stream of images from all angles. One tower, a sleek, 33-foot telescoping pole built by Anduril Industries, the defense contractor run by Oculus founder Palmer Luckey and funded by PayPal co-founder and GOP megadonor Peter Thiel, was capable of recording night-vision images and spotting human beings up to 1.7 miles away.
My companions were Tucson-based photographers documenting the growing landscape of border surveillance mechanisms. They were working with the Electronic Frontier Foundation (EFF) to map all such towers along the border—a vast, expensive, and increasingly automated network that is now effectively an electronic wall.
Less than 10 miles away, in El Paso, the importance of automated surveillance and artificial intelligence was the theme of the annual Border Security Expo, a massive conference that drew roughly 1,700 attendees in 2023. Many of them were employees of the “industry partners” that market and sell such technology to representatives from 46 state agencies; they were joined by overseas buyers and a handful of academics. “Border Security Expo [is] the best place to gain access to this hard-to-reach, highly qualified audience,” the exhibitor prospectus boasted.
Inside the exhibition hall, visitors were met by a Verizon-built robot dog performing an uncanny march: forward like an old-timey soldier, side to side like a jittery crab.
“This is a partnership,” Border Patrol Chief Jason Owens said during the opening panel. “We’re expressing to you the things that we need and relying on the big brains in this room and your companies to come up with the next way forward.”
The conference featured panels such as “Border of the Future” and “DHS Acquisition: Tone From the Top.” Inside the exhibition hall—a large, fluorescent-lit chamber resembling the belly of a colossal blimp—visitors were met by a Verizon-built robot dog performing an uncanny march: forward like an old-timey soldier, side to side like a jittery crab.
Automated ground surveillance vehicles, as the dogs are known, can lend “a helping hand (or ‘paw’) with new technology that can assist with enhancing the capabilities of Customs and Border Protection (CBP) personnel, while simultaneously increasing their safety downrange.” These dogs are ready to be outfitted with cameras, sensors, and radio.
Other exhibitors featured “No BS” canine food to help optimize real-life working dogs; virtual reality training systems that sharpen law enforcement’s shooting skills; all-terrain tanks; heavy-duty cargo e-bikes; mobile fences; and guns, of course. Occasionally, the displays reminded attendees of the true adversary most border technologies targeted: people. A heat-sensing camera that works from miles away, for instance, and sensors that can detect a human heartbeat hidden in a vehicle.
Like nearly everyone else, CBP leadership has a serious case of AI fever, and officials make clear that this kind of technology acts as a “force multiplier” to Border Patrol agents themselves. Surveillance tower cameras and drones can alert agents when a vehicle or person comes into view and help CBP ascertain the threat level. AI tools also help screen cargo coming into the country and scour data from CBP One—a notoriously glitchy app that asylum seekers must use to navigate their legal process—to detect cases of suspicious identity.
Just last year, CBP’s AI monitoring system flagged “a suspicious pattern in the border crossing history” of a car in Southern California. Upon further review, 75 kilos of drugs were found in the vehicle, and the driver was arrested.
The Biden administration has insisted on the responsible use of AI. Yet such guidelines rarely have any teeth—and could be easily dismantled under a new administration.
AI and machine learning at the border aren’t entirely new. The first autonomous towers were installed in 2018, and two years later, the Trump administration brokered a deal with Anduril. (Luckey, the brother-in-law of Florida Rep. Matt Gaetz, donated $100,000 toward Trump’s inaugural celebrations in 2017.) Trump’s bombastic rhetoric has always focused on mass deportations and his cherished border wall. But all along his administration was building a surveillance apparatus that the Biden White House has since expanded—and that could be the single most powerful tool in the hands of a second Trump administration to carry out extrajudicial exclusion at the US border. One that could be used against its citizens, too.
But this would first require Border Patrol to effectively analyze all the data it’s collecting. At the Expo, Border Patrol officials routinely noted that AI surveillance tools have amassed so much information that CBP needs machine learning tools to make any sense of it. “In the past we were looking at hundreds of millions of nodes of data,” said Ray Shuler, DHS’s assistant director of cyber and operations technology. “Now we’re looking at multibillion-node graphs.” Shuler says his unit alone is running up to 400 servers at any given time and is constantly in need of more storage capacity.
But managing this data, said Joshua Powell, CBP’s director of AI implementation, is what “will give us the advantage over our adversary. They have the resources. They have the money. They have connections.” Officials invoked the “adversary” repeatedly throughout the convention—a militarized villain, and a mushy one at that. But who, exactly, was this well-heeled, tricked-out, tech-savvy enemy amassing at our gates? It could be anyone—which is why we need constant surveillance.
For its part, the Biden administration has insisted on the responsible use of AI. In 2023, DHS named tech specialist Eric Hysen as the department’s first chief AI officer, issued a departmental framework for responsible AI, and launched the AI Corps, a team of 50 experts to better monitor and implement the technology. “AI is going to make us bigger and faster and stronger—it’s not going to make us any less accountable,” Hysen claims. Yet as EFF investigations director Dave Maass points out, such administrative guidelines and bodies rarely have any teeth—and could be easily dismissed or dismantled under a new administration.
At the Expo, Border Patrol officials insisted that their work is saving lives—and that the latest technological acquisitions support this mission. But some border tech is inherited from war zones or inspired by them; notably, many of the vendors also contract with the Department of Defense. As Harvard researcher Petra Molnar, author of The Walls Have Eyes, argues, border zones are perfect test sites for technologies with questionable human rights applications, since they’re often obscured from public view. Once refined and normalized at the border, they can more easily slip into the mainstream—iris scans at airports, for instance, or automated traffic tickets issued to anyone who runs red lights (which the Texas legislature outlawed in 2019). Maass argues that surveillance reliant upon algorithmic technology can make mistakes—with consequences that can be dangerous for the person on the other end.
The future of the border is one of endless expansion and externalization—well staffed and automated, optimized by artificial intelligence, and implemented by men in green.
Those of us who live far from the border might imagine surveillance towers situated in remote swaths of the desert. Some of them are. But often they are positioned in border towns near schools and downtown shopping centers, on Native American reservations, and alongside the highways where we all drive. “We are actually talking about a surveillance network that monitors communities…that have nothing to do with transport or crime,” Maass told me. “They are just living their lives, doing their thing, but they’ve got the CBP tower looking in their window.”
US border defense is ever-expanding in reach—moving not just deep into our country’s interior, but also far beyond our own walls. “Most people don’t know there are Border Patrol agents today deployed around the globe in dangerous areas,” Chief Owens explained to the crowd on the Expo’s opening day, “with the express purpose of making sure that they can stop the threat from ever reaching our borders in the first place.”
Powell, too, spoke of the need to “[push] our borders out beyond what we’ve traditionally been focused on, an outline of the United States…out through Western and Eastern hemispheres to identify who is thinking, planning, and attempting to make entry into the US and then why.” By collecting and sharing data with intelligence agencies across international borders, the thinking goes, we’ll be better able to defend our own. Ultimately, the future of the border is one of endless expansion and externalization—well staffed and automated, optimized by artificial intelligence, and implemented by men in green.
When he was in El Paso for the Expo, Dugan Meyer, a graduate student and one of the photographers contributing to EFF’s countersurveillance map, headed out in the late afternoon to New Mexico’s Mount Cristo Rey—a bare, rugged peak adorned with a giant white statue of Christ from the 1930s. Here, the insistent advance of the border wall is briefly broken by the base of the mountain and becomes a major hotspot for Border Patrol activity, migrant crossings, and deaths. That night, Meyer hung out near the wall in the brush, watching as helicopters patrolled the skies while Border Patrol trucks scoured the dark. At one point, Meyer heard someone climb the wall from the Mexican side and drop down into the United States. Meyer saw the man step carefully over railroad tracks and then disappear into the scrub.
Patrol forces reappeared within minutes, as if something had alerted them to the crossing. Perhaps something had. For the next hour, Meyer watched the hunt. The Border Patrol has access to heat-seeking cameras, surveillance towers, drones, helicopters, and ground sensors. The man was racing this vast, mechanized force, all odds seemingly against him, and yet every day, in spite of the billions of dollars spent to stop them, people like him manage to get through. For Border Patrol authorities, however, this becomes one more piece of evidence that they need more of everything: funding, agents, towers, robot dogs.
This endless expansion is the reality the Expo was selling—and, maybe more importantly, banking on.
