President Donald Trump's plan to build a wall on the U.S.-Mexico could backfire, as a newly unearthed report shows that the number of illegal drug smuggling tunnels jumped considerably after a border fence was build and security added.
"Illegal tunneling activity on the southwest border of the United States represents a significant and persistent threat to border security and will likely remain so in the near future," reads a 2010 report from the Immigration and Customs Enforcement Homeland Security Investigations office, which was made public earlier this month.
"The rise in illegal tunneling is likely a response to increasingly heightened border security," it adds.
A 2012 report from the Department of Homeland Security’s Inspector General found that "Tunnel activity has been on the rise since the first reported discovery in 1990, though the trend has accelerated since 2006," though the report is heavily redacted.
"The success of Operation Jump Start, the newly created border fencing and subsequent elevation in Border Patrol agent levels" forced criminals "to seek alternative methods for transporting drugs across the U.S./Mexico border," it reads.
"It is possible that the simultaneous rise in tunneling activity during this time period was the result of heightened border security," the report said.
