More than 40 percent of Americans believe that the 9/11 Commission Report that investigated the Sept. 11, 2001, terrorist attacks is a cover-up, according to a recent poll. And nearly half surveyed said the attacks should be reinvestigated. In May, a Zogby International poll of adults found that 42 percent of adults polled believe the U.S. government and the 9/11 Commission concealed or refused to investigate critical evidence" that contradicts the official explanation of the attacks. The Zogby poll was sponsored by a leading activist group, 911 Truth.org, which is highly skeptical of the official report published in July 2004. "With half the country believing as we do, (the poll) is some form of vindication," said Jonathan Gold, a former member of 911 Truth's steering committee. Gold, who lives in Plymouth Meeting, complained that major media has ignored the truth movement. "The media is not covering that fact that 45 percent of voting Americans believe we should have another investigation," he said. "It deserves attention."
