I certainly agree with that. But if they can also identify them as they are approaching the border, there should be some who otherwise would make it over that we can stop.
Also, we need the military outright defending the border, not simply getting coffee for CBP.
We see them on the fence all the time. Nothing we can do about it other than to let them know that we see them. If they dont care to get caught they just climb right over. We can not do anything to anyone climbing the fence.
