Right. And let's have virtual fences to divide property lines, and virtual grates on stores, and virtual glass between bank tellers and patrons. And since he's the head of homeland security, how about virtual barriers at airports and virtual metal detectors and virtual cockpit doors. Lets all be one big happy open world. Get a clue, Chertoff.
And as far as what he said about real fences not working, talk to Israel and China. And does the name Wall Street ring a bell?? It got it's name from the wall/fence that the dutch put up to keep out the indians. We should just call it Virtual Street!
And here you can find the up-to-date thinking of the Dynasty in China which built the Great Wall to keep out Ghengis Khan. It was a huge public works project that involved real, manual labor. You will not find support for 21st century technological solutions, though occasionally you might find some sentimentality for high tech workers being outsourced to India. Luddites do not appreciate the deterrance of predator drones on the border, and sentimentally denounce any suggestion that we shoot invaders. We have magic thinking instead. Just seal the borders. Get out that Seal-o-matic you ordered from TV and seal away!
They should remove the fence around the White House and put in a virtual one.
Chertoff should also have a virtual job.
