It would seem the best cover for a terrorist would be as a cabbie or truckdriver! They're obviously above suspicion! It's hard to believe this sort of thing goes on today. Probably the initiative of some bright think-tank kid who, at 19 years old, has no sense of learning from the past. I think the biggest problem is that we don't live long enough to learn from our predecessors mistakes and by the time the next "reds under the bed" wave of panic occurs, no-one will listen to the old guys who remember the last one!
