Shulan Sun: How would you introduce the main arguments of Borderland Circuitry in 2026, especially in light of the U.S. government’s increased intervention in Latin American politics over the past few years?
Ana Muñiz: In Borderland Circuitry, I argue three main points. I deconstruct immigration data system processing, sharing, and algorithms to: (1) Map information exchange, a form of digital border construction, between local law enforcement agencies primarily in the Western and Southwestern United States; federal law enforcement agencies in the United States; and law enforcement agencies in Mexico, Central America, and the Caribbean; (2) Examine how authorities construct people – both US citizens and noncitizens, particularly alleged gang members – as dangerous through technology and target them for forced movement and incapacitation; (3) Consider the way in which immigration surveillance makes life precarious on the individual level; on the macro level, creates an environment conducive to the broad growth of authoritarianism (for example, through the use of homeland security and border control agents to police domestic racial justice protests); and how racial criminalization through digital data enables land destruction along the U.S.-Mexico border.
Shulan Sun: In your methodological appendix, you describe a “scorched earth approach” to access, one that relied heavily on archival research and four Freedom of Information Act lawsuits to compel the state to release its data. You note that this is a method that often gains access once and never again. For scholars interested in institutional ethnography who now face even tighter restrictions on transparency, how does litigation itself function as a form of ethnographic practice? What does it reveal about the inner culture and logics of these agencies that more conventional methods, such as interviews, might not make visible?
Ana Muñiz: Great question! To clarify, I am NOT referring to archival research and the FOIA lawsuits as a method that gains access once and never again, which is what this question appears to imply. Rather, I am referring to conducting an ethnography within a law enforcement agency, releasing a book based on that research that is highly critical of that law enforcement agency, and using the research results to engage in community organizing, policy, and litigation. On a practical level, no law enforcement agency is going to allow me access again to conduct observation or interviews, so I have turned to public records lawsuits to get access to novel material.
For Borderland Circuitry, I first conducted participant observation and interviews with attorneys who represent gang-labeled clients going through an immigration process, either those facing immigration enforcement or those seeking an immigration status change. Through the information gathered from the participant observation and interviews, I expanded my institutional ethnography into organizational mapping and textual analysis through public records requests, and subsequent lawsuits, to access internal documents pertaining to law enforcement information systems.
There are challenges and strengths to every method. One challenge of interviews is that I do not necessarily believe a lot of what people say, so archival methods can corroborate or contradict narratives proposed in interviews. Furthermore, memory is incredibly unreliable. Tracking documents through archival channels enables the researcher to see documentation of what happened at the time, which can be more reliable than what people remember in hindsight. I also think there is a lot to be gained by analyzing the process of accessing these documents, as your question implies. The necessity of filing a lawsuit to simply get a public records request acknowledged, and the subsequent negotiations to compel the release of documents, reveal how law enforcement agencies think of themselves – not as public agencies accountable to a public but as elite private clubs who are entitled to keep public information from the public.
Shulan Sun: Your work moves beyond a simple binary of inclusion and exclusion to engage with scholarship on “differential inclusion,” in which migrants are formally incorporated into the body politic while being positioned within subordinate racial hierarchies. How does the technological infrastructure of interoperability—the connective tissue that allows disparate databases to talk to one another—actively produce this paradoxical condition? In your account, how do data systems not simply record migrant lives, but mediate forms of partial belonging and exclusion at the same time?
Ana Muñiz: For most of my career, I have studied how police, through gang designation, can legally treat Black and Brown men, particularly in working class urban neighborhoods, as a criminalized and dehumanized class. I am fascinated, and deeply disturbed, by how effectively law enforcement at various jurisdictional levels weaponize gang labels to formally incorporate people into the body politic while subordinating them in the racial hierarchy. So, this dynamic is by no means exclusive to migrants but rather, occurs in myriad ways to different politicized and racialized groupings of people, and we should not treat the migrant experience as exceptional in this way. Differential inclusion is a longstanding practice in the U.S. Data systems are merely a new way to do an old thing, and I think it is important we do not get dazzled by the technology aspect.
However, one thing law enforcement is using technology to accomplish is legitimizing illegitimate designations. For example, it is common for ICE to state that an immigrant is a “known or suspected gang member” and list the source as “database” without specification or evidence. Regardless of its veracity, the allegation’s presence in a database imbues it with an authority and legitimacy. It is information laundering in which the racist and subjective process of gang categorization is washed away from the digital data double.
Shulan Sun: Throughout the book, you describe an “interfacial regime” in which subjective, and at times fabricated, assessments by frontline officers acquire durability as they circulate across local, federal, and international systems. How does this process effectively decouple the border from physical territory? What does this suggest about the future of the nation-state when identity, risk, and deportability can be enforced far from any geographic frontier, including through forms of externalized incapacitation in migrants’ home countries?
Ana Muñiz: I think it is important here to go back to classic work like Gloria Anzaldúa’s Borderlands/La Frontera, which conceptualizes the border not only as a physical space but also as an ontological condition. The border can be something one carries in the body and the mind in both generative and challenging ways. Interoperable databases allow questionable labels to attach to one’s body and circulate within and even outside of U.S. territory. I do think we are already seeing physical borders becoming less important in determining exclusion. The nation-state can make anyone foreign through categorization. I think we will see more stripping of citizenship and other statuses based on racialized categories, political expression, and other designations. And the recent example of incarcerating people deported from the U.S. in prisons in El Salvador (including people who are not from El Salvador) points to how these systems of exclusion, forced movement, and incapacitation can develop into global circuits.
Shulan Sun: While your analysis is deeply structural, the book is anchored by visceral human stories that make the consequences of digital surveillance infrastructures palpable. One case that stayed with me in particular is Karla’s asylum interview, which was transformed from a legal proceeding into an extractive exercise in intelligence gathering and data production. Was this case, or another like it, especially formative in shaping your decision to frame the book around “circuitry” rather than the wall alone? What about this moment crystallized for you the transformation of subjective assessments into what you describe as a “regime of bodily horror” that follows people across borders?
Ana Muñiz: It actually works the other way around for me; the book always started with the circuitry, which I then decided to literally ground – in the land, in the architecture of the wall, in the bodies of people – for several reasons. First, much surveillance work focuses on data flows and assemblages with vague references to how surveillance has disparate effects for people of different races, genders, and so on. I think this work sometimes forgets, or at least does not do a good job of showing how, ultimately, digital data hits the land and the body like a bomb.
Second, above all else, I am a writer. Technology in and of itself does not make for a compelling narrative. We need to see the people whom the technology affects. Relatedly, this is not really about the technology. Policing, including immigration enforcement, is about the promulgation of a racial hierarchy, and technological developments provide only the latest tools in a long line of tools dedicated to this task. Ultimately, the horror of the dynamics I cover in Borderland Circuitry do not have a technological solution. They will only be addressed by facing basic questions about who is considered human and who is not.
The example of Karla was not really a crystalizing moment for me. Rather, it was an exercise I had seen different types of law enforcement (local police officers, federal immigration agents, school police, and more) carry out many, many times. It was deeply familiar. The archival analysis allowed me, for the first time, to trace how the subjective, biased, racialized, and inaccurate assessments gleaned through these exercises travel through different agencies and jurisdiction through interoperable databases.
However, it is important to remember that these assessments are not just practical intelligence-gathering strategies used by the state. They also shape how the people being interrogated understand themselves and their place in the world. These assessments are intended to terrorize and to humiliate. I write about this in a 2022 article in Critical Criminology entitled “Gang Phantasmagoria: How Racialized Gang Allegations Haunt Immigration Legal Work,” where I argue that this kind of extensive questioning about gang association in asylum interviews constitutes a state mechanism of racial terror.
