Poll: Confidence in Anti-Terror Response Drops

In another sign of eroding public trust in the aftermath of Hurricane Katrina, confidence in the federal government's ability to respond to a terrorist attack unleashing nuclear or radioactive materials has fallen sharply in the hurricane's aftermath.

At the same time, there's a positive post-Katrina development: Many more Americans (albeit still a minority) now have their own meet-up plan should an emergency occur.

Overall, 52 percent in this ABC News poll do express confidence in the government's ability to respond effectively to a nuclear or radiological terrorist attack – but that's fallen from 78 percent in late August, likely a result of the troubled hurricane response.

In terms of their own preparation, 40 percent now say they have a plan for how family members will communicate, or where to meet, if there's a serious emergency. That's jumped from 26 percent in August. Katrina again seems a likely factor.

In another result relevant to the recent hurricanes, 55 percent think the area where they live could be evacuated in a timely fashion in the event of a terrorist attack or natural disaster. But 42 percent are not confident that could happen – and just two in 10 are "very" confident their area could be evacuated rapidly.

This poll, including a detailed look at Americans' preparedness and concerns about possible terrorist attacks, supports the ABC News series "Loose Nukes on Main Street: The New Terror Threat," airing Sunday, Oct. 9 to Friday, Oct. 14. The series focuses on the security of radiological materials – or the lack thereof. The bulk of this survey was conducted in August, with some questions repeated after the recent hurricanes.
