WATCH: Rise of the Super Drug Tunnels: California's Losing Fight Against Smugglers

"You can't fight markets," says David Shirk, associate professor of international relations and director of the Justice in Mexico project at the University of San Diego. "When a market reaches a certain size, you can't fight it."

He and his colleagues have spent much of their careers doing just that, discovering more than 200 drug tunnels under the California-Mexico border since the inception of the task force in 1990. 

"We want to make it so unattractive to do the type of work that they do, that they'll go somewhere else," says Garcia.
