MICKEY KAUS: “You know that expensive ‘virtual’ border fence the Obama administration recently cancelled? It actually worked, acording to Janice Kephart of the Center for Immigration Studies. There were big problems with the prototype, but they fixed them. No wonder it got cancelled! … I had always assumed the ‘virtual fence’ was a fancy-sounding Bush administration scam to let the government weasel out of building a real, nonvirtual fence (of the sort that works well enough in California, which is why illegal immigrants and smugglers now cross in Arizona). But maybe both sorts of fences can work.”
