I submit that a virtual fence is not a fence. A serious way means building some miles of actual fence. That is what keeps the illegal immigrants from crossing illegally into the United States. In combination with UAVs. helicopter. fixedwing surveillancethere is surveillance actually in other ways. as well. which we do not need to get intothere are sensors. there are cameras. there are people on patrol on horseback. on threewheeled vehicles. on fourwheeled vehicles. and you put all of those things together. and we can build a combination of actual and virtual fencing that creates the ability to control the border. This is what you do if you are serious about controlling the border.
