Look at what they found in San Diego:
A tunnel designed to smuggle drugs from Tijuana, Mexico, to San Diego is equipped with electricity, ventilation and a rail system, U.S. authorities said Thursday, making it one of the more sophisticated secret passages discovered along the U.S.-Mexico border.
Authorities seized more than 8 tons of marijuana and 325 pounds of cocaine in connection with the discovery, U.S. Immigration and Customs Enforcement said. Three suspects were in U.S. custody.
The tunnel links warehouses in Tijuana and San Diego’s Otay Mesa industrial area. The area is filled with nondescript warehouses, making it easier to conceal trucks being loaded with drugs.
Imagine if that sort of creative effort and entrepreneurial effort were going into the productive economy, instead of simply into moving banned plant products across arbitrary lines.
