You do realize that the majority of the wall that POTUS wants to put up with run across private lands that will have to be taken by eminent domain, right?
Build the wall everywhere possible without using eminent domain and let the rest take the brunt of the border crosser’s. Eventually they may change their minds.
That’s the reason Im more supportive of the landowners themselves putting up Fences in whatever manner is beneficial to them. The cost is prohibitive for an individual to build. If it funnels illegals to choose alternative routes, then those landowners will be making decisions.
