A fence alone will not work. Anyone who’s been to the border knows it.
The concept of a fence in Texas is ludicrous.
The border is the center of a meandering river. A fence can’t be built in a river. If the fence is constructed on the Texas bank, the river is effectively ceded to mexico. Then there is the matter of the law. If the Latrinos reach the center of the unprotected river they become subject to US law and granted a deportation trial. The fence in effect guarantees all who cross the river instant asylum.
The concept of a fence is a joke, a pie in the sky irrational nothingness.
