“A rope and a drone makes it a lot easier to scale that wall design.”
Not impregnable, but effective at deterring the great bulk of people. Like they say, 50 foot wall, 51 foot ladder.
Although any barrier can be breached, gotten over or under, there are some real thresholds of significance, along the cost/effectiveness curve. Stopping unassisted climbers is one of them. They are the great bulk of border crossers.
The height of 30 feet itself is an effective deterrent. A lot of people willing to scale 18 foot barriers will balk at 30 foot. 30 feet is a significant risk of death in a fall - more than half will die from it (LD50). The fatality rate from 18 foot falls is under 1%.
Making a barrier that cannot be free climbed (without equipment) is a significant threshold. A big round barrel top that offers no handholds and is too big to reach around, puts a hard stop to unaided scaling.
These heavy steel (concrete filled) bollards are beyond the ability of common people to breach as well. Jose Handyman can get a hold of battery powered tools that can cut through sheet metal fences (an everyday occurrence on the border), but bollards have been standing for years on the border with virtually no maintenance. They can literally withstand a bomb, or being rammed by a speeding dump truck.
The six foot deep concrete bases also does away with a common infiltration technique whereby border crossers dig enough of a space to slide under the old landing mat (sheet metal) barriers, just minutes before their attempt (before patrols can detect the “tunnel”. To dig under the bollard foundation is mutli-hour hard effort, if you are right at the base (where you would be easily seen). It does away with common folk tunneling.
These see through bollard barriers are now being installed with constant camera surveillance, and efforts are underway to link the cameras with unblinking artificial intelligence software, to reliably alert Border Patrol of anyone approaching the barrier.
At the article link, you can watch the video of this poor border crosser falling. That fast detection and response may have been what saved his life, but it would also mean that folks who did successfully scale the barrier with ropes or ladders, would be running from the cops as soon as they landed.
Thanks for the information. I think the crazy fit illegals will try to find a way to scale them. (If there are any fit illegals crossing the boarder at all). What about transportation of drugs? Just curious what the solution for that with this wall setting.
