Caught and released. Heck most just look for someone to surrender to and demand sanctuary.
When the first invader caravan was coming, Trump said they would not get in. The border patrol used some riot control agents, the press screamed “gassing children!”, and that was that. Now the border patrol just fills out forms and transports the invaders further into our homeland.
The word is out: Show up at the border and you get in. (and you get to stay). Some additional fencing, now or years from now, doesn’t change the equation. Rapid removals are needed. Do it Mr. President.
