Anyone who thinks that will work needs to think about how effective it would be if our prisons had no walls and no locking doors.
How does anyone who believes that explain all the illegals in this country now?
I already posted again saying that I have no preference for how they do it and that I'm sure a mix of methods are needed. But prisons are controlled (somewhat) by the guards. It wouldn't work if you just had walls, they would get out. But a wall is ok as long as it works. 2,000 miles is a very long wall.
