Did you read the story?

"Border agents monitor the cameras and other detection equipment so they can respond to intrusions."
Great to have the cameras to monitor if you have the back-up to do something. How many robberies and crimes do we see monitored, and no-one to respond before it's too late? I know the fence alone isn't enough, but I also know cameras are not the sole answer either. The fence and cameras alone aren't enough if we don't have people to respond. I just don't trust our government to actually go to the length necessary and afraid they will try the least effective methods first....especially since it's something they don't appear to want to control anyway.
