Mexico wants US state attorneys general to investigate migrant deaths in Immigration and Customs Enforcement custody. It sounds like a bold, righteous stand for human rights. It sounds like a sovereign nation leveraging every legal avenue to protect its citizens abroad.
It is actually a masterclass in political theater.
This diplomatic maneuver is designed to generate headlines while avoiding any actual structural change. It relies on a lazy consensus that assumes goodwill on the part of the Mexican government and legal viability in the US federal system. Neither exists.
If you want to understand why migrants keep dying in detention centers, you have to stop buying into the performative outrage of bilateral press releases. You have to look at the cold, hard mechanics of constitutional law, sovereign hypocrisy, and the real economic incentives driving the detention machine.
The Constitutional Wall State Attorneys General Cannot Cross
The entire premise of Mexico’s appeal to state attorneys general (AGs) collapses under the weight of basic constitutional law.
I have spent years analyzing federal-state jurisdictional clashes. The reality is simple: state AGs have virtually zero authority to regulate, police, or prosecute federal immigration agencies.
Under the Supremacy Clause of the US Constitution, federal law preempts state law when it comes to areas of exclusive federal domain. Immigration is the textbook definition of a federal domain. The landmark Supreme Court ruling in Arizona v. United States (2012) made it incredibly clear that states cannot establish their own immigration policies or interfere with federal enforcement.
When a death occurs in an ICE facility, that facility operates under federal contracts, federal guidelines, and federal jurisdiction. Even if a facility is run by a private corporation like GEO Group or CoreCivic, it operates as an extension of the federal government’s enforcement apparatus.
What happens when a state AG tries to launch a criminal investigation into a federal officer or a federal contractor operating under federal mandates? They run headfirst into federal immunity defenses. The doctrine of derivative sovereign immunity shielding federal contractors is a legal fortress.
Mexico’s legal advisors know this. They know that a state AG in California, Texas, or Georgia cannot simply march into a federal facility with a local search warrant. By asking state AGs to do the impossible, the Mexican government gets to look proactive while knowing they are pointing their fingers at a closed door. It is cheap political cover.
The Ciudad Juarez Elephant in the Room
To understand the sheer cynicism of Mexico's demands, we have to look south of the border.
In March 2023, a fire broke out at a government-run migrant detention center in Ciudad Juárez, right across the border from El Paso, Texas. Forty migrants died. They did not die because of an uncontrollable act of god; they died because guards belonging to Mexico’s National Migration Institute (INM) walked away and left them locked in a burning cell.
The Ciudad Juárez tragedy was not an isolated incident. It was the predictable result of a Mexican immigration system that is chronically underfunded, deeply corrupt, and outsourced to militarized security forces.
For years, Mexico has acted as America's de facto southern border patrol. Under pressure from both Democratic and Republican administrations in Washington, Mexico has aggressively detained and deported hundreds of thousands of Central and South American migrants before they can even reach the US border.
The Mexican government run detention centers are notorious for extortion, physical abuse, and lack of basic medical care. Yet, we see no sweeping internal investigations, no systemic overhauls of the INM, and no accountability for the high-level officials who orchestrate these policies.
When the Mexican government demands that US state AGs investigate ICE, they are not acting out of a pure commitment to migrant safety. They are trying to shift the spotlight away from their own horrific track record. It is a classic diversion tactic: pointing out the speck in your neighbor's eye while ignoring the plank in your own.
The Private Capital Shell Game
Let’s talk about how the US detention system actually works, because the mainstream media loves to simplify it into a cartoonish battle between good and evil.
The vast majority of ICE detainees are housed in facilities run by private prison corporations. These companies operate on a business model that requires a steady flow of human beings to maintain profit margins. They sign Intergovernmental Service Agreements (IGSAs) with local counties, which then subcontract the work to private operators.
This creates a highly fragmented liability shield:
- ICE claims it is not responsible because the facility is operated by a private contractor or a local county.
- The Private Contractor claims it is merely following federal guidelines and is shielded by federal contracts.
- The Local County claims it is just a pass-through entity for federal funds and has no real operational control.
If you want to stop deaths in custody, you do not ask a state AG to launch a symbolic probe. You have to dismantle this contract structure. You have to target the financial flows.
But doing that requires legislative action in Washington. It requires rewriting federal procurement laws and cutting off the lobbying money that flows from private prison firms into the campaign coffers of federal lawmakers on both sides of the aisle.
By framing this as a state-level law enforcement issue, Mexico's demand actually protects this federal cash machine. It suggests that the problem is merely a few bad apples in specific state-located facilities, rather than a federally mandated, profit-driven system designed to minimize operational costs—including medical care—at every turn.
Dismantling the Premise of the "Detention Reform" Debate
If you look at the questions policy analysts and journalists constantly ask about this issue, you realize they are asking the wrong things entirely. Let's dismantle the standard talking points.
Can state civil rights laws force ICE to reform?
No. State-level civil rights lawsuits against federal agencies are routinely dismissed on jurisdictional grounds. While states like California have passed laws attempting to phase out private detention centers, these laws have faced fierce legal challenges from the federal government and private operators, who argue that states cannot dictate how the federal government houses its detainees. The legal system is built to protect federal supremacy, not state-level humanitarian interventions.
Is more oversight the answer to ending custody deaths?
We have plenty of oversight. The Department of Homeland Security's Office of Inspector General (OIG) and the Office for Civil Rights and Civil Liberties (CRCL) publish damning reports year after year detailing the horrific conditions, medical neglect, and systemic failures inside ICE facilities.
The problem is not a lack of information; it is a lack of consequence. These oversight bodies have no enforcement power. Their reports are filed away, ignored, or used as political ammunition by opposition parties, while the actual conditions inside the facilities remain completely unchanged.
What is the actual solution to migrant deaths in custody?
The only way to stop deaths in custody is to drastically reduce the number of people in custody. Detention is a policy choice, not a legal necessity. The US government has the authority to use alternatives to detention, such as community-based monitoring programs, which are a fraction of the cost and do not result in people dying of treatable medical conditions behind razor wire.
But reducing detention numbers hurts the bottom line of the private prison lobby and deprives politicians of the visual theater of "tough" border enforcement.
The Harsh Truth of Bilateral Border Politics
We have to stop treating international diplomacy like a high school debate match where the side with the most moral arguments wins.
Mexico’s diplomatic note to the US is a transaction. It is currency to be traded in future negotiations over trade, drug interdiction, and water rights. By creating a public fuss over ICE deaths, Mexico establishes a bargaining chip.
Later, behind closed doors, Mexican negotiators can offer to quiet down their rhetoric on human rights in exchange for concessions on tariff exemptions or agricultural access. It is a cynical, calculated game played with the lives of the most vulnerable people on earth.
If the Mexican government were serious about protecting its citizens, it would stop cooperating with the US's externalized border enforcement policies. It would refuse to accept deportees under legally questionable programs, and it would invest the resources necessary to make its own southern territory safe for transit.
Instead, we get letters sent to state attorneys general. We get performative outrage. We get a lazy news cycle that reports on the "clash" between nations without ever explaining that both governments are deeply complicit in the very system they pretend to fight.
The next time you see a headline about a sovereign state demanding accountability for migrant deaths, do not look at the demands. Look at the contracts. Look at the jurisdictional walls. Look at the money. That is where the truth is, and it is a truth that neither Washington nor Mexico City wants you to see.
