I agree on your points on a concrete wall. I would add razor wire on top. I dont care for the steel because who wants to see what the nasty group on the other side is doing. Let the MSM go to Mexico if they choose to photograph them.

I believe it’s the border patrol that’s asking for the see-thru fencing. Trump is, as usual, listening to those of whom he asks advice. Every time I see razor wire, or such, I imagine fabric similar to that of the gloves the installers wear being thrown over the top of it in the middle of the night at some remote spot. You can imagine roadside stands for razor-proof fabric.
Border Patrol.
Thanks. I can understand a security forces need to see what’s going on on the other side of the concrete wall. But with so much tiny camera tech; solar power and drone tech—I don’t see that as a significant problem. And I think it is far less a problem than the steel would become given enough time and evildoers inventiveness.
