 Close quote. An analogy from outside the box. On a flight from Minneapolis to Washington, D.C., somewhere over Cleveland, the pilot gets a call from TSA letting him know that they finally watched the videotape of the conveyor belt and the carry-on of the guy in 19A who's sweating and sitting next to the nice young family from Spokane, has two guns, a can of sarin gas, a gas mask, a parachute, a pound of C4, a falsified passport, five kilos of uncut Peruvian cocaine, and child porn flying on a one-way ticket.
