If I've sounded a wee bit overwrought in recent columns, it's because America is seizing up before our eyes. And I'm a little bewildered by how many Americans can't see it. I see that chap at LaGuardia with on his chest and government bureaucrats in his pants. And I wonder if America's exceptional attitudinal swagger isn't providing a discreet cover for the withering of liberty. Sometimes an in-your-face attitude blinds you to what's going on under your nose.
