Fourteen years after 9/11, Truthers, as they've been pejoratively labeled since 2001, have not gone away. In 2006, Zogby found that 42 percent of Americans nationally believed the U.S. "concealed or refused to investigate critical evidence that contradicts their official explanation of the September 11th attacks," and that "there has been a cover-up." There are millions of people in the U.S. who believe the official story of 9/11 is ... false. That's not a fringe group. It's possible that you know a friend who's a Truther. Or a dentist. Or a bartender. Maybe they just haven't told you. Bob Mcllvaine lost his son, Bobby, in the north tower of the World Trade Center. He joined a group called 9/11 Families for Peaceful Tomorrows, [and] helped lead a march of 250,000 anti-war protesters in New York. "I didn't want to be a victim," he said. "I wanted to have change." The turning point came when he attended the 9/11 Commission hearings. "I felt then that this whole thing has been a big lie," he said. "People just don't want to talk about it." His status as the father of a victim hasn't protected him from critics of the Truther camp. But he also says that after one Fox News segment a few years ago, presidential candidate Mike Huckabee and Fox host Geraldo Rivera both told him footage of WTC 7 looked like a controlled demolition to them. Mcllvaine also said he gets anonymous calls from the CIA or FBI encouraging him and saying they agree it was an inside job.
