OK, maybe I’m being negative...but the way it looks to me a simple grappling hook would make it very easy to go over the top. I would rather they used a large rounded top that a grappling hook can’t grasp onto. I guess this is better than nothing but I just do not think it will stop them.
“I still really don’t like that design. The vertical posts make it all too easy to climb.”

The current funding (2018 Omnibus) limited designs to those previously proven, which includes the 18 - 30 foot bollards, and anti-climb plates that we are seeing. They were the most effective designs deployed so far. In fact, they work very well, but are not perfect.
Hopefully, the new budget they are working on for next year, will at least allow the big round barrel tops, that tested so well on the prototypes.
30 foot bollards with a 5 or 6 foot barrel top would require specialized skills and equipment - basically no more migrants at all, only the occasional drug cartel.
The new barriers going in now also include wide clearances which are alarmed and under camera surveillance, with good patrol road to speed enforcement response. As the barriers get harder, they also have less time to get past them.
