The Download: investigating deaths at the US border's "virtual wall"

The US spent billions on border surveillance. Why can't it catch people before they die? When José Morales Bernal crossed the border into the US in April 2024, the day before his 32nd birthday, he was within range of three surveillance towers equipped with cameras and AI to automatically detect and track people. If the system worked as intended, Morales should have been apprehended. If he needed medical help, agents were trained to provide it. Instead, Morales died just 360 feet from the closest tower.
