Book excerpt: Homeland Security and Governmental Affairs Committee Chairman Joe Lieberman, ID-Conn., and Ranking Member Susan Collins, R-Maine., Tuesday warned the American people not to lower their guard against terrorism now that the tenth anniversary of 9/11 has passed. At the Committee's annual hearing to assess the terrorist threat against the U.S., Homeland Security Secretary Janet Napolitano, FBI Director Robert Mueller and National Counterterrorism Center Director Matthew Olsen agreed that while al Qaeda's leadership has been degraded, the terrorist threat was more "complex and diverse" than it was 10 years ago, and violent Islamist extremists working by themselves in this country, perhaps U.S. citizens, posed a particular threat.
