More than a third of the American public suspects that federal officials assisted in the 9/11 terrorist attacks or took no action to stop them so the United States could go to war in the Middle East, according to a new Scripps Howard/Ohio University poll.

The national survey of 1,010 adults also found that anger against the federal government is at record levels, with 54 percent saying they "personally are more angry" at the government than they used to be.

Widespread resentment and alienation toward the national government appears to be fueling a growing acceptance of conspiracy theories about the 2001 attacks on the World Trade Center and the Pentagon.

Suspicions that the 9/11 attacks were "an inside job" - the common phrase used by conspiracy theorists on the Internet - quickly have become nearly as popular as decades-old conspiracy theories that the federal government was responsible for President John F. Kennedy's assassination and that it has covered up proof of space aliens.

Seventy percent of people who give credence to these theories also say they've become angrier with the federal government than they used to be.

Thirty-six percent of respondents overall said it is "very likely" or "somewhat likely" that federal officials either participated in the attacks on the World Trade Center and the Pentagon or took no action to stop them "because they wanted the United States to go to war in the Middle East."

"One out of three sounds high, but that may very well be right," said Lee Hamilton, former vice chairman of the National Commission on Terrorist Attacks Upon the United States (also called the 9/11 commission.) His congressionally appointed investigation concluded that federal officials bungled their attempts to prevent, but did not participate in, the attacks by al Qaeda five years ago.

"A lot of people I've encountered believe the U.S. government was involved," Hamilton said. "Many say the government planned the whole thing. Of course, we don't think the evidence leads that way at all."

The poll also found that 16 percent of Americans speculate that secretly planted explosives, not burning passenger jets, were the real reason the massive twin towers of the World Trade Center collapsed.

Conspiracy groups for at least two years have also questioned why the World Trade Center collapsed when fires that heavily damaged similar skyscrapers around the world did not cause such destruction. Sixteen percent said it's "very likely" or "somewhat likely" that "the collapse of the twin towers in New York was aided by explosives secretly planted in the two buildings." [...]
