The precise locations of the U.S. government's high-tech surveillance towers along the U.S-Mexico border are being made public for the first time as part of a mapping project by the Electronic Frontier Foundation. While the Department of Homeland Security's investment of more than a billion dollars into a so-called virtual wall between the U.S. and Mexico is a matter of public record, the government does not disclose where these towers are located, despite privacy concerns of residents of both countries and the fact that individual towers are plainly visible to observers. The surveillance tower map is the result of a year's work steered by EFF Director of Investigations Dave Maass. As border surveillance towers have multiplied across the southern border, so too have they become increasingly sophisticated, packing a panoply of powerful cameras, microphones, lasers, radar antennae, and other sensors. Companies like Anduril and Google have reaped major government paydays by promising to automate the border-watching process with migrant-detecting artificial intelligence. Opponents of these modern towers, bristling with always-watching sensors, argue the increasing computerization of border security will lead inevitably to the dehumanization of an already thoroughly dehumanizing undertaking. Nobody can say for certain how many people have died attempting to cross the U.S.-Mexico border in the recent age of militarization and surveillance. Researchers estimate that the minimum is at least 10,000 dead.
