According to a July poll conducted by Scripps News Service, one-third of Americans think the government either carried out the 9/11 attacks or intentionally allowed them to happen in order to provide a pretext for war in the Middle East. This is at once alarming and unsurprising. Alarming, because if tens of millions of Americans really believe their government was complicit in the murder of 3,000 of their fellow citizens, they seem remarkably sanguine about this fact. By and large, life continues as before, even though tens of millions of people apparently believe they are being governed by mass murderers. Unsurprising, because the government these Americans suspect of complicity in 9/11 has acquired a justified reputation for deception: weapons of mass destruction, secret prisons, illegal wiretapping. What else are they hiding?
This pattern of deception has not only fed diffuse public cynicism but has provided an opening for alternate theories of 9/11 to flourish. As these theories — propounded by the so-called 9/11 Truth Movement — seep toward the edges of the mainstream, they have raised the specter of the return (if it ever left) of what Richard Hofstadter famously described as "the paranoid style in American politics." But the real danger posed by the Truth Movement isn't paranoia. Rather, the danger is that it will discredit and deform the salutary skepticism Americans increasingly show toward their leaders.
The Truth Movement's recent growth can be largely attributed to the Internet-distributed documentary "Loose Change." A low-budget film produced by two 20-somethings that purports to debunk the official story of 9/11, it's been viewed over the Internet millions of times. Complementing "Loose Change" are the more highbrow offerings of a handful of writers and scholars, many of whom are associated with Scholars for 9/11 Truth. Two of these academics, retired theologian David Ray Griffin and retired Brigham Young University physics professor Steven Jones, have written books and articles that serve as the movement's canon. Videos of their lectures circulate among the burgeoning portions of the Internet devoted to the cause of the "truthers." A variety of groups have chapters across the country and organize conferences that draw hundreds. In the last election cycle, the website www.911truth.org even produced a questionnaire with pointed inquiries for candidates, just like the U.S. Chamber of Commerce or the Sierra Club. The Truth Movement's relationship to the truth may be tenuous, but that it is a movement is no longer in doubt.
Truth activists often maintain they are simply "raising questions," and as such tend to focus with dogged persistence on physical minutiae: the lampposts near the Pentagon that should have been knocked down by Flight 77, the altitude in Pennsylvania at which cellphones on Flight 93 should have stopped working, the temperature at which jet fuel burns and at which steel melts. They then use these perceived inconsistencies to argue that the central events of 9/11 — the plane hitting the Pentagon, the towers collapsing — were not what they appeared to be. So: The eyewitness accounts of those who heard explosions in the World Trade Center, combined with the facts that jet fuel burns at 1,500 degrees Fahrenheit and steel melts at 2,500, shows that the towers were brought down by controlled explosions from inside the buildings, not by the planes crashing into them.
If the official story is wrong, then what did happen? As you might expect, there's quite a bit of dissension on this point. Like any movement, the Truth Movement is beset by internecine fights between different factions: those who subscribe to what are termed LIHOP theories (that the government "let it happen on purpose") and the more radical MIHOP ("made it happen on purpose") contingent. Even within these groups, there are divisions: Some believe the WTC was detonated with explosives after the planes hit and some don't even think there were any planes.
