I wasn’t knocking your suggestions. It is just a general question. I remember they even did a show called The Bridge (now cancelled) that used tunnels in their stories.

The bottom line is that you'll never keep all illegal immigrants out, in the same way as there's nothing that we can do that would completely prevent any other type of crime. Advocates of open borders use this as a ridiculous excuse to do absolutely nothing - by their logic of "we can't stop them all, so let's not even try," we shouldn't bother trying to stop theft or vandalism either.

If we can establish a border security system that would slow the illegal invasion from a flood to a manageable trickle, that would be a great leap forward compared to what we have now. I'm not dogmatic in demanding that it be a fence/wall along the entire border, in some places increased surveillance will do the job. The point is that something is better than the near-nothing that we have in place today.

My idea with a border fence is similar to my approach to home security. A dedicated thief could break into my home at night, but it is clearly much harder to get into my home than other homes. I don’t expect many thieves to try hard enough to find out what happens if they do get in. At some point, they might even decide not to burglarize homes.

Similarly, if we make the border moderately secure and then enforce immigration law uniformly against on those who do make it in, it won’t be worth the effort to try to cross our border illegally. Force them to make long tunnels and then destroy the tunnels as they are discovered. At some point, it will become easier to just follow the law.
