Isn’t that the whole point of building a border wall? A way to force people to cross at safe boarder crossings? The problem is that as border patrols have become more vigilant people are crossing in more and more dangerous places. The “safe routes” of the past often had access to streams or other water sources. So if you have 80% of people crossing at these safe, but illegal, places it makes sense to patrol these areas. So once that happened you had more and more people crossing illegally in areas like the Sonoran desert that has almost no water.
Do you suggest we increase border patrols in the most rugged areas and continue to add water stations? Border patrol already intentionally avoids the water stations because groups had complained that they used them to trap illegal immigrants. The immigrant supporters say that increased border patrols just make it so that people continue to chose more dangerous routes
So what solution is there to maintain border sovereignty while making it safe? Putting up border fence or detection grids with quick response teams to apprehend them before they die would make the most sense, but liberals are completely opposed to closing the borders in those ways. Short of saying that we will not pickup illegal immigrants they seem bound and determined to avoid capture even if it means walking through the desert in the height of summer with no food or water.
