Much of the criticism has been contemptuous and hysterical. Various experts have gathered bits of Umar Farouk Abdulmutallab’s biography. Since they can string the facts together to accurately predict the past, they thunder, the intelligence services should have been able to connect the dots to predict the future.

Dick Cheney argues that the error was caused by some ideological choice. Arlen Specter screams for more technology  full-body examining devices. “We thought that had been remedied,” said Senator Kit Bond, as if omniscience could be accomplished with legislation.

Many people seem to be in the middle of a religious crisis of faith. All the gods they believe in  technology, technocracy, centralized government control  have failed them in this instance.

In a mature nation, President Obama could go on TV and say, “Listen, we’re doing the best we can, but some terrorists are bound to get through.” But this is apparently a country that must be spoken to in childish ways. The original line out of the White House was that the system worked. Don’t worry, little Johnny.

When that didn’t work the official line went to the other extreme. “I consider that totally unacceptable,” Obama said. I’m really mad, Johnny. But don’t worry, I’ll make it all better.

Meanwhile, the Transportation Security Administration has to be seen doing something, so it added another layer to its stage play, “Security Theater”  more baggage regulations, more in-flight restrictions.

At some point, it’s worth pointing out that it wasn’t the centralized system that stopped terrorism in this instance. As with the shoe bomber, as with the plane that went down in Shanksville, Pa., it was decentralized citizen action. The plot was foiled by nonexpert civilians who had the advantage of the concrete information right in front of them  and the spirit to take the initiative.

For better or worse, over the past 50 years we have concentrated authority in centralized agencies and reduced the role of decentralized citizen action. We’ve done this in many spheres of life. Maybe that’s wise, maybe it’s not. But we shouldn’t imagine that these centralized institutions are going to work perfectly or even well most of the time. It would be nice if we reacted to their inevitable failures not with rabid denunciation and cynicism, but with a little resiliency, an awareness that human systems fail and bad things will happen and we don’t have to lose our heads every time they do.
