NOGALES, Mexico — Crouched in the spiky terrain near this border city, a veteran smuggler known as Flaco points to the steel border fence and describes how he has taken drugs and people into the United States for more than three decades. His smuggling techniques include everything from throwing drugs over in gigantic catapults to hiding them in the engine cars of freight trains to making side tunnels off the cross-border sewage system.
When asked whether the border wall promised by President Trump will stop smugglers, he smiles. “This is never going to stop, neither the narco trafficking nor the illegals,” he says. “There will be more tunnels. More holes. If it doesn’t go over, it will go under.”
What will change? The fees that criminal networks charge to transport people and contraband across the border. Every time the wall goes up, so do smuggling profits.
