Hill.TV poll: 42 percent think not enough done to prevent another 9/11

More than 4 in 10 Americans, 42 percent, say "too little" is being done to prevent another Sept. 11–style attack, according to a new American Barometer poll conducted by Hill.TV and the HarrisX polling company.

Nearly half of those surveyed in the poll, 46 percent, said the U.S. is doing "just about enough" to prevent another terror attack, while 12 percent said the U.S. is doing more than enough to prevent a similar attack.

Gallup editor-in-chief Frank Newport told Hill.TV's Joe Concha that the plurality of Americans saying the U.S. is doing enough to prevent such an attack shows that the public is generally fine with how the U.S. has handled terror threats since the 2001.

"The plurality in this poll says things are OK in terms of handling terrorism probably reflects the fact that we have not had, luckily, any kind of major terror incident in the U.S. recently," Newport said on Hill.TV's "What's America Thinking."

The poll's release falls on the 17th anniversary of the Sept. 11 attacks at the World Trade Center in New York, the Pentagon in Northern Virginia and in Shanksville, Pa., killing nearly 3,000 people and injuring thousands more.

A number of smaller-scale terror attacks have taken place on U.S. soil since 2001, including the Boston Marathon bombings in 2013, the San Bernardino shooting in 2015 and the Orlando Pulse Nightclub shooting in 2016. 

The American Barometer poll was conducted Sept. 8–9 among 1,000 registered voters and has a margin of error of 3.1 percentage points.
