Sorry if I strike a political cord without meaning to. I heard that the latest plan may be to build a steel wall,fence,barrier.... on the southern border. I would think that would be easy to deconstruct with a plasma cutter. I'm guessing that many of you have thought along these same lines.

Add "plasma cutters will go through it" to the list of excuses.

They can dig tunnels under it, you know.

They can launch people on trampolines, too.

Catapults.

Hang gliders.

Teleportations not that far off.

:-)
But I believe that there is a history of tunnels having been dug to
cross the border.

cheers,

There has indeed. However..one of the additions to the "fence" is
sysmic detection units. They are quite easy to place..its a well
proven technology. Think of it as a form of "land sonar"

The tunnels have been dug in the basements of houses in urban areas to
other urban areas across the border. Having it in the middle of
bum**** nowhere is too easy to spot via drone.


Yes, there are novel ways of detecting human traffic out in the
open. I have joked in the past of machine gun turrets accessed by the internet with a credit card. To be a little more realistic I would think that perhaps stationing guards every so often, atop the wall, with some of these advanced intrusion detection schemes (video, sound, motion, IR...) might play. These invaders are clever so the cat and mouse game will go on. Of course if you lop off a finger and launch the invader back over the wall with the Mexi-pult you find fewer repeat offenders.
