Down below them, the taxicab with the Arab in the back slows down to sublight speed and winds its way down a twisting slalom course of Jersey barriers with .50-caliber machine gun nests strategically placed here and there. It comes to a stop in front of an STD device, straddling an open pit where EBGOC boys stand with dogs and high-powered spotlights to look up its skirt for bombs or NBCI (nuclear-biological-chemical-informational) agents in the undercarriage. Meanwhile, the driver gets out and pops the hood and trunk so that more Feds can inspect them; another Fed leans against the window next to the Arab and grills him through the window.
