“There was a time when Mexican vendors sold water jugs with a map glued to the side. The map displayed various mountain peaks, and migrants were directed to follow the promontories to highways where they would be picked up. Towers made that impossible. A 10-mile journey became a 20-mile march, and migrants increasingly relied on smugglers to guide them through arroyos, along mountainsides, weaving a path beyond sight of the towers. This is what Boyce and Chambers have termed CBP’s “corral apparatus,” an intentional strategy to funnel migrants into “a narrower corridor of movement” where they’re more likely to become isolated, confused, and where “physiological strain, suffering and mortality are likely to be greatest.” The very point of the surveillance tower placement, they contend, was to increase the difficulty of the journey.
“An initial strategy was to channel people into certain areas, to funnel them to a place where it’s easier to apprehend them,” James Lewis, who had advised on SBInet, told me. “That’s not good from a crosser perspective because they’re forced into more inhospitable areas, and the casualty rate goes up.”
This corralling has an official name, it’s called “prevention through deterrence.” The Clinton administration devised this strategy and CBP still practices it today — consciously or not. During the program’s first stages, in the mid-1990s, the U.S. raised walls near border cities with the intent to push migrants into the desert. Metrics like “a shift in flow” of migratory routes and “fee increase by smugglers” were signs of effectiveness. And deaths were an expected outcome. “Illegal entrants crossing through remote, uninhabited expanses of land and sea along the border,” the policy said, will “find themselves in mortal danger.” The government likely figured this would be an added deterrent, as stories of dead fathers and siblings filtered back through migrant networks. That is not what happened. Instead, as people left broken economies and rampant violence for the U.S., the death toll along the border soared and still the migrants came.”
