There is a video posted on the internet of a tall bollard design that looked impressive but then showed illegals climbing up it with ease, much like climbing a palm tree.

Easy.

From the US side...

See how it can make it taller?

The bollard design is actually just a starting point, a solid framework to be customized to the situation at hand.

...... With that flat plate in place at the top of the wall .... I doubt if anybody could actually get over. It's one thing to scale the slats .... It's a totally different ballgame getting over without being able to grab onto anything to scale the rest of the wall over the top ..... Without that plate however .... is another story.

But note they do not show them getting over it....

Simple solution? Make the edges sharp as a razor blade, few people would be willing to grab them.
