Question for Anyone:
How do you protect against deep tunnels under the Trump Wall?
Thinly veiled anti wall propaganda?
100% border security is not possible. If we could get up to 97% or greater security, that would be satisfactory.
Sonar or similar technology might detect some tunnels, and then we'd have to depend on local law enforcement and the BP to detect strange activity that might indicate a tunnel exit on the US side.
Doubt we'd ever get any help from the Mexican side.

Consult with Israel and follow their advice, of course.

You listen for them being dug or used. Locate them and destroy them.

Ground-based sensors - we have them, not in the cities where they are worthless, but in the desert where they work wonderfully.
i. First, build the wall.
2. Second, install high-quality sensors seeking and
processing sounds and other “signals” from the earth to
let us locate the tunnels,
3. Third, use high speed drills to drill down to the
tunnels and
4. Fourth, drop high-impact explosives down the
drill holes into the tunnels and then detonate them -
thereby causing massive “cave-ins”.
5. No tunnels. No “coyotes”. No tears.
Same way you protect against ladders and such. You treat all such incursions as invasion attempts, and give patrolling Army units full discretion to shoot to kill.
No fence will work, unless there are serious enforced consequences for attempting to breach it. And not much of a fence is needed, if people thinking of crossing see the potential consequences as unacceptable.
