ok, destroy the tunnels

14. It goes pretty well

What's not going well is ordinary gun violence which kills some 18,000 people a year in the US, and yet we don't shell cities into rubble over it.

If the point is to plug the tunnels, then doing it from the end where the tunnel comes out is going to be a whole lot more effective than doing it by shelling some random building somewhere, which does not even put a tunnel out of commission.

However, the US does do periodic sweeps with ground penetrating radar and other technology. Certainly, if they were being used for mass organized violence, you bet there would be seismic sensors along the entire border.

Tunnelling activity is not difficult to seismically detect, and shelling Tijuana would be a stupid approach to dealing with smuggling tunnels.

Since 2006, federal authorities have detected at least 80 cross-border smuggling tunnels, most of them in California and Arizona, and seized some 100 tons of narcotics associated with them.

If you are referring to the recent wave of minors crossing the border, that has nothing to do with tunnels. In fact, their whole plan is to find and surrender to the first border agent they see, so they can get into the process. That's very different from smugglers and laborers.
