As always in America, what actually happened today near Boston braided entirely into what was being shown and said, so that the two became inseparable. There were two, and then one, terrorists on the run in a Boston suburb; there were two, and then one, terrorists at large in the American imagination. The strange grim day wore on into the blue-and-white flashing night, with the apparent and blessedly peaceful and rightly well-applauded surrender of a more or less intact Dzhokhar Tsarnaev.

Then, of course, the cops spoke and officials stepped forward to claim credit, or at least a piece of the spotlight, for the arrest. U.S. Attorney Carmen Ortiz announced that now “my journey begins.” One imagined the real heroes and heroines of the occasion standing back in the shadows, smiling ironically at the politicians’ posturing. All the while, though, you couldn’t help separate thinking about terrorism from thinking about the way that we represent it.

The incomparable A. J. Liebling wrote once that there are three kinds of journalists: the reporter, who says what he’s seen; the interpretive reporter, who says what he thinks is the meaning of what he’s seen; and the expert, who says what he thinks is the meaning of what he hasn’t seen. The first two—reporters and interpretive reporters—have been largely undermined by economics and incuriosity. But the third category never stops growing. We are now a nation of experts, with millions of people who know the meaning of everything that they haven’t actually experienced.

There are still paradoxes and ironies, surprising heroes and unexpected goats in the new reign. Sometimes the professional experts really are undone by the amateurs. Waking up at six-thirty on Friday morning and hearing what had happened in the night, I followed my own generational instincts, honed on Vietnam and Watergate and the Gulf War, and turned on the television to see the usual stern-jawed “terrorism experts” being stern, scary, and obviously not knowing what the hell they were talking about. Within an hour, with the help of my eighteen-year-old, who insisted on turning from television toward the Web, we had the Tsarnaev brothers’ names, school history, wrestling involvement, vKontakte (Russian Facebook) pages, YouTube videos, and boxing photos.

And we already had a glimpse of how this might be a tragedy of assimilation and its discontents. A well-liked student at a good public school, a Golden Gloves boxer—somehow they had transformed their souls in ways that made it possible for them to casually drop devices meant to rip human flesh apart next to an eight-year-old boy and his family. Of course, the pseudo-expertise of the official experts was more than matched by the pseudo-expertise of the amateurs. The night before, the attempt to hang this thing on a poor—and still missing—Indian-American student at Brown, had been crazy, not to mention libelous, not to mention heartbreaking to his family.

However the details turn out, this is certainly a tragic story about America far more than it is a tale about the exotic elsewhere. Whatever had happened, it had happened here. Surprises surely await us as we go on, but an intuitive scenario—in which an older brother who had struggled with the promise and disillusion of American life and turned to extremist Islam for comfort dominated and seduced a younger brother not born or made for violence—seemed plausible. But all of our experience suggests that it is not “fundamentalism” alone but an aching tension between modernity and a false picture of a purer fundamentalist past that makes terrorists.

And it was an American story, too, in what could only be called a hysterical and insular overreaction that allowed it to become the sole national narrative. I happened to be in London on 7/7—a far more deadly and frightening terrorist attack—and by 7 P.M. on that horrible day, with the terrorists still at large (they were dead already, but no one knew that), the red double-decker buses were rolling and the traffic was turning and life, though hardly normal, was determinedly going on. The decision to shut down Boston, though doubtless made in good faith and from honest anxiety, seemed like an undue surrender to the power of the terrorist act—as did, indeed, the readiness to turn over the entire attention of the nation to a violent, scary, tragic, lurid but, in the larger scheme of things, ultimately small threat to the public peace.

The toxic combination of round-the-clock cable television—does anyone now recall the killer of Gianni Versace, who claimed exactly the same kind of attention then as Dzhokhar Tsarnaev did today?—and an already exaggerated sense of the risk of terrorism turned a horrible story of maiming and death and cruelty into a national epic of fear. What terrorists want is to terrify people; Americans always oblige.

Experts tell us the meaning of what they haven’t seen; poets and novelists tell us the meaning of what they haven’t seen, either, but have somehow managed to fully imagine. Maybe the literature of terrorism, from Conrad to Updike (and let us not forget Tolstoy, fascinated by the Chechens), can now throw a little light on how apparently likable kids become cold-hearted killers. Acts of imagination are different from acts of projection: one kind terrifies; the other clarifies.
