On July 13, in Biddeford, Maine, a Colombian migrant named Johan Sebastián Durán was shot and killed while sitting in his car with his three-year-old daughter 1. The man who fired the weapon, ICE agent David Brouillette, had a documented history of domestic violence and severe mental illness 1. This is not a story about a single bad actor; it is a story about the institutional architecture that placed a known risk in a position of unchecked authority over a person with almost no legal standing.
Durán’s legal status is the first mechanism at work. As an undocumented migrant, his presence in the United States placed him entirely within the discretionary power of federal immigration enforcement. That power, in this case, was wielded by an agent whose own record should have disqualified him from carrying a firearm, let alone making life-or-death decisions. The gap between what the system knew about Brouillette and what it allowed him to do is where Durán fell through.
The same pattern—a person with limited institutional power encountering a system that fails to check its own—repeats across jurisdictions. In San Cristóbal, Colombia, lottery vendor Miguel Antonio Lucas Valenzuela died hours after being released from police custody, where he had been held for operating an unauthorized payment device 11. His family alleges abuse; an independent investigation has been demanded 11. The alleged crime was a regulatory infraction. The consequence was a death.
In Guerrero, Mexico, indigenous leader Jesús Plácido Galindo was arrested on homicide charges stemming from a 2021 killing 4. Galindo is a promoter of the Consejo Indígena y Popular de Guerrero-Emiliano Zapata, an organization that represents communities with historically limited access to legal recourse. The charge is serious; the timing and context raise questions about whether the legal system is being used to silence advocacy. The distinction between a legitimate prosecution and a weaponized one is often invisible from the outside, but the burden of proof falls on the state to show it is not the latter.
These cases share a structural feature: the person harmed occupied a position of legal or social vulnerability—migrant, informal worker, indigenous activist—while the person or institution causing the harm operated with broad discretion and minimal accountability. The ICE agent had a known history of abuse; the police in San Cristóbal had custody of Lucas; the Guerrero prosecutor’s office has a history of targeting community leaders. The institutional mechanisms that should have protected these individuals—background checks, oversight, independent investigations—failed.
What matters most for the reader is not the outrage, but the unresolved question: what would it take to close the gap between what a system knows and what it allows? The records exist. The advocates are speaking. The consequence of leaving the gap open is measured in lives lost, families shattered, and trust destroyed. The decision about whether to close it belongs to the institutions that hold the power—and to the public that holds them accountable.
