Frist’s piece represents no change whatsoever, with its hilarious assertion that planning to plan for the preparation of security plans is sufficient to begin a mass legalization program. But what suddenly struck me was that the frequent talk of a “virtual fence” along the Mexican border reminds of nothing so much as a mime, trapped in his virtual box. If we had mimes trying to sneak into the country, then a virtual fence might be enough, but since we don’t, maybe a real one is called for.
