Terrorism was a focus of US mayors meeting in Madison, Wisconsin. Even as Washington debated whether Homeland Security should become a cabinet-level agency, the debate at the US Conference of Mayors in Madison centered on what role the cities will play. Columbia Mayor Darwin Hindman attended the conference. He said a recent survey disclosed most mayors worry about chemical or biological terrorism. They want more federal money for threat detection and emergency response equipment. The threat came home to Hindman when it came to light that a suspected terrorist cell operated in Columbia in the late 90s, and that one individual linked to Osama bin Laden lived in Columbia.
