Patrick Smith asks why his baby scissors keep getting snatched by airport security:
When it came right down to it, the success of the Sept. 11 attacks had nothing -- nothing -- to do with box cutters. The hijackers could have used anything. They were not exploiting a weakness in luggage screening, but rather a weakness in our mind-set -- our understanding and expectations of what a hijacking was and how it would unfold. The hijackers weren't relying on weapons, they were relying on the element of surprise.
All of that is different now. For several reasons, from passenger awareness to armored cockpit doors, the in-flight takeover scheme has long been off the table as a viable M.O. for an attack. It was off the table before the first of the twin towers had crumbled to the ground. Why don't we see this? Although a certain anxious fixation would have been excusable in the immediate aftermath of the 2001 attacks, here it is a decade later and we're still pawing through people's bags in a hunt for what are effectively harmless items.
