I lived inside the Berlin Wall from ‘82-’85, and witnessed some escape attempts (and one successful one).
Most died trying.
The outer ring was in many places a well marked fence.
Next inside was a dog run, followed by a minefield, with guard towers. The guard towers also remotely operated machine guns that faced along the wall itself.
The wall was 14’ tall, with a 3’ diameter cylinder than ran along the top of it.
The mines were quite sensitive - as many rabbits found out...
We need a 2,000 mile long double wall with concertina wire between the two walls and on our side of the second wall. We need motion sensors to detect criminals crossing illegally or tunneling.
We need real penalties for criminals who enter our country illegally, or who overstay a visa, and for the criminals who hire them.
We need to do away with chain migration and with birthright citizenship for the babies born to those who were not legal residents and thus not fully “subject to the jurisdiction” of our government when they gave birth.
Most of all, we need a patriotic president (the opposite of the current occupant of our White House) who will enforce the laws we have.
Fencing and walls may be part of border security — they are not the entirety of it. Not even if you paint big gold letters on it.
Question is this, why have we NOT seen build proposals?
I have not heard a word about the best viable doable, cost effective per mile design yet.
Concrete pre cast dropped between vertical I beams?
Vertical wire?
Electrified?
Built like in Israel, or like something from Jurassic Park?
Or an elevated causeway with just a simple double fence, but fence is reactive.
Or a fence that does not look like a fence? Some unique new design?
