It is fairly obvious a wall will do nothing to stop drugs and/or illegal immigration. https://www.msn.com/en-us/news/us/a...th-along-arizona-border/ar-BBS8b6P?li=BBnbfcL TUCSON — Mexican authorities uncovered another tunnel in Nogales, Sonora — across the border from Nogales, Arizona — which they suspect was used to smuggle drugs and people across the U.S.-Mexico border. It's the third time they have made such a discovery in less than a month, and comes amid President Donald Trump's demand for funding to build more physical barriers along the U.S.-Mexico border. Mexican Federal Police on Wednesday posted a short video of the tunnel on Twitter. Police said the tunnel measured about 32 feet in length, but offered few other details, such as the location or how they found it.
