This illustrates the importance of having a physical barrier to prevent illegals from sneaking in like this in the first place.
Like The Doors' Jim Morrison said long ago:
The West is the best
GET HERE, and we'll do the rest.
Once they're here, it becomes very difficult and time-consuming to get rid of them, because of our legal system.
All they have to do is set foot on our soil, and "we do the rest".
The goal should be to prevent them from touching American soil.
And nothing will do that better than a border barrier.
