Virtual walls detect Mexicans AS and AFTER they cross and they are apprehended and welcomed in to begin processing. I want an actual wall that is damned tough to get over.
What we need is a moat along our border wall, with lots of pirhannas, alligators, and cottonmouths. Warning signs every 100 feet in English, Spanish, Arabic, and Chinese.
The actual wall that is damned tough to get over (under or through), is already funded, and is now the biggest construction project in the USA.
With ladders and ropes, people climb Mount Everest. So some reduced number will climb even the best of walls. Therefore, the walls themselves must be watched and guarded.
These Anduril systems will be like the unblinking, sleepless eyes of hundreds, or thousands of human guards.
Not just more, but actually better -able to see in the dark, and more.
Before you complain about wanting human guards, I assure you that Border Patrol is hiring up. These are in addition to the human guards. Force multipliers.
