Unless Donald Trump manages to defeat Hillary Clinton, the whole point of a border wall is moot. Should he win, there’s the additional trick of getting Mexico to pay for the wall. But what would prevent illegals from, say, digging a tunnel underneath the border wall?

Most of CNN’s viewers are still having a good laugh over Trump telling Anderson Cooper about his “hardening,” but others are stuck on his promise to equip his wall with “all sorts of things,” including “tunnel technology” to prevent illegals from burrowing their way into the United States.

Hold on, now: Israel employs seismic detectors that detect underground activity. Maybe that’s what he was talking about.
