Right and the other point is that even if you can’t build it in some parts, you can in many others. I have no idea the percentage, but let’s build the fence where we can. Perry is against any fence, which I think is just plain dumb.
Perry does concede a need for walls or fencing in urban areas, which already exists in many places. But if we're ever serious about controlling the border, double fencing will have to be built everywhere illegals are able to cross into the US. Unless there are natural barriers to illegal entries, fencing and personnel are needed.
I get you. This might help.
Read ari’s post #14.
There are many more things that can be done to physically secure the border beyond a fence.
*That* is what the American people are crying out for. Not just a fence, but for a secure border.
