Part 6/12:
The construction and operation of these tunnels require substantial capital, engineering expertise, and logistical support, often involving university-affiliated students coerced or incentivized into designing these underground networks. Professional architects and engineers plan these routes to withstand collapses, earthquakes, or detection, ensuring a steady flow of contraband and profits.
The cartels’ capacity to adapt is relentless. When authorities succeed in cracking down on one method or route—such as the physical border walls—they pivot to underground pathways, overland routes, or even maritime channels. They shift from methamphetamine to fentanyl, then to human smuggling, and even infant trafficking when necessary.
