Part 5/7:
The existence of state-of-the-art tunnels presents significant challenges for border security. Traditional detection methods often fall short when confronting these highly engineered passages. The tunnels' advanced ventilation systems, reinforced structures, and discreet entry and exit points mean law enforcement agencies must employ sophisticated technology, like ground-penetrating radar and seismic sensors, to locate and dismantle them.
Furthermore, the financial stakes are high. Smugglers prefer to invest in these durable tunnels because losing a shipment or a trafficker through an inspection is costly. The precision engineering ensures the flow of narcotics and cash remains uninterrupted, fueling the ongoing drug crisis in the United States.
