re: The "they will just use a ladder" wall arguement

If you need motion detectors to apprehend border crossers, why do you need a wall? Just set up sensors, and when they go off, send in the patrol. Money = saved.

We already use them. Why not integrate them with the wall to catch the few that will still attempt with the wall in place? Also, it is pretty obvious that it is easier to stop one at a time than thousands en masse. This isn't that difficult.
