Detection and response has them already on our soil and is far more manpower intensive. I want 1800 miles of fence, with as much of it as possible with 30’ fences and a solid road, as well as loads of concertina wire in between. Let border patrol catch any attempted crossers suspended between the two fences, above ground, with tech detection and truck patrol.
Seeing how they can climb over even the tall fences now with rope ladders is just sickening.
“Seeing how they can climb over even the tall fences now with rope ladders is just sickening.”
Any obstacle can be mechanically overcome, given enough opportunity (Mt Everest is my favorite example). Critics will say, if you build a 30 foot wall, they will build a 31 foot ladder.
The doctrine of the the Army’s Combat Engineers, is that any obstacle must be kept under observation, to maintain its effectiveness. By that, they mean both being monitored, and being subject to fire, to prevent the enemy from having the time to needed to breach the obstacle. The Border patrol equivalent to placing an area under fire, is their ability to intercept and arrest.
The basic border calculus, is: Intercept time = Detection time + Disappearing time.
A see through barrier improves detection time - cameras can stare deep into Mexico, for anyone approaching the barrier. With solid barrier, often the earliest opportunity to detect, is when a head pops over the top of the wall.
In urban areas, illegals can sometimes disappear in just one minute - hopping into a car, running into a shopping mall, or jumping through back yards. In some rural areas, they have to walk for days, but response time to intercept is also longer.
So in rural areas, detection and response capability become more important. In fact, if your detection and response is good enough, you don’t really need a barrier at all in many places, if all it does is slow down crossers with ropes and ladders for a few minutes.
The new bollards provide a strong obstacle - even a big truck with a suicide driver cannot ram through. With anti-climb plate on top, and concertina on the American side, the great bulk of climbers (even with ladders and ropes) are deterred.
But in addition to the obstacle, they are wired with sensors and alarms that form a continuous “linear detection system”, or tripwire of sorts, that is very difficult to cross undetected. They also generally include good roads for to improved response times. That is why Border Patrol likes to call it “Wall System”. Not only does it reduce the number of crossers, it also improves detection and response.
