Americans’ collective level of worry about terrorism measured in the USA Today/Gallup poll, conducted June 8-9, is the lowest recorded since August 2004 (34%) and down sharply from the all-time high of 59% recorded in October 2001, just after the Sept. 11 attacks. The latest poll finds 30% who say they are not too worried about being a victim of terrorism and 34% who say they are not at all worried.
