I Think the Wall is Coming

1/19/18 Idaho Statesman:

SAN DIEGO Recent assaults by tactical teams on prototypes of President Donald Trump's proposed wall with Mexico found their imposing heights should stop border crossers, The Associated Press has learned, a finding that's likely to please security hawks but raise concerns about costs and environmental damage.

Military special forces based in Florida and U.S. Customs and Border Protection special units spent three weeks trying to breach and scale the eight models in San Diego, using jackhammers, saws, torches and other tools and climbing devices, a U.S. official with direct knowledge of the rigorous testing told the AP on condition of anonymity because the information was not authorized for public release.

Each model was to be 18 to 30 feet (5 to 9 meters) high, and contractors built at or near the maximum, which is roughly twice as high as many existing barriers. Ronald Vitiello, the agency's acting deputy commissioner, said after visiting the prototypes in October that he was struck most by their height.

"environmental damage"?  Environmentalist are claiming they are too tall for birds or insects.
