A tunnel found Monday night on the Arizona-Mexico border near downtown Nogales was the ninth such excavation detected in the Border Patrol’s Tucson sector since October.
The tunnels are a vivid reminder that it’s futile to depend on a border wall to stop illegal immigration.
But the fact that the new tunnel was found by technology does underscore the importance of investing in more high-tech means to secure our border.
Since fiscal 2003, 34 tunnels have been found in the Tucson sector.
Two other tunnels beneath Nogales were found Thanksgiving week.
Many of the tunnels have been elaborate enough to accommodate not only the trafficking of guns and money, but also of illegal immigrants.
We hope more high-tech means will be deployed to detect and dismantle these secret passageways into the U.S.
