What we really need to stop is the travesty of “slats” as a wall. Undoubtedly the recommendation of a drug lord (likely Chapo, at least) bought off border patrol union. But the idea that slats, which agents on our side can readily be shot from/through, are safer than the solid concrete and rebar wall that Trump campaigned on is on its face ridiculous. Slats mean that drugs and other contraband can be smartly and readily passed from anywhere along the border.
The politically correct people want slats so that border patrol can see the poor migrants on the other side needing help.
