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.

They can also shoot through it. Although that could work both ways...
