The Download: investigating deaths at the US border’s “virtual wall”
US border cameras miss many deaths, showing tech fails in life‑saving roles.

Why Now
MIT Technology Review’s 15‑month probe mapped 4,000 death sites against 600 surveillance towers, revealing systemic blind spots.
What Happened
The study found at least 138 migrant deaths within tower range since 2022, with over half likely seen by cameras. Broken towers, faulty detection algorithms, and unresponsive agents were common failures.
Why It Matters
These gaps mean the government’s $1 billion expansion of the virtual wall could still let people die unnoticed, undermining public safety and trust in AI surveillance.
The Limitation
The analysis relies on publicly available data and may miss unreported incidents or misclassify tower coverage.
What You Can Do
Review the MIT map of death sites and advocate for stricter tower maintenance and real‑time human oversight.
