I agree with this, but I would counter it makes even more pressing we secure the border in the most efficient manner, instead applying politically expedient gimmicks which we already know have a high degree of vulnerability.
I mean, at least in some areas we already have a multi-layered system with in land checkpoints (which predate any wall), but even those, being locally static, can be planned for.
Ultimately, proactive intelligence work likely has the best return on investment when it comes to organized crime (and again, not a wall)
