Trump's shutdown has affected TRA, Coast Guard, and other essential border security functions. He says he's doing it, because if he doesn't do it, the democrats won't do what he wants.
So much for the "foremost responsibility."
Problem is, a wall won't work. And even if it did work, most illegal aliens don't get here by sneaking across rural border zones. They either come in legally and just overstay, or sneak in illegally at border checkpoints.
In this case, the wall is like putting bars over your chimney, and leaving the front door unlocked.
Let's see...do you lock you car doors?
Yep. But I don't lock my tree. For the same reason it would be foolish to build the wall. Yes, people sometimes steal trees, but it's far more likely that someone would want to break into my car, so I focus on that.
Yep. But I don't lock my chimney.
Do you take whatever security measures possible to ensure your safety?
No. For example, I don't have a concrete wall around my yard, or even "steel slats." Why not? Because I have limited funds and I focus on things that are effective and within my budget. I use lighting and locks at entry points actually used by burglars.
People have fences and gates around their dwellings. Same thing with the wall. Porous borders are an open invitation to illegals.
As you learned, most people who are here illegally either entered legally at points of entry, or managed to slip by airports, border crossings, etc. And the wall is no more than a speed bump for someone who wants to cross. Ladders, reciprocating saws, etc are easy to come by.
