Why do we need the wall? If Mexico won't police their side of the border, why do we have a free trade agreement with them? Why can't we just pressure Mexico to prevent illegal border crossings? The wall will someday be used to keep Americans in.
And when they say suspected terroists are apprehended at the border, why were they allowed into the western hemishpere?
Interpol and FBI know who is flying on what flight at all times. Why don't they have them arrested at the airport?
I'm on the fence on the wall. I see a need, of course, but why don't we pressure Mexico to help us? If we can't rely on Mexico, why do we give them so much in aid and free trade? Something fucked up with the equation.
