FBI: pipe bomb in Colorado was "domestic terrorism"

A pipe bomb discovered in a Colorado shopping mall may have been the work of a "domestic terrorist," and may have been connected to the 12th anniversary of the shooting rampage at nearby Columbine High School, according to FBI investigators. Firefighters found the homemade bomb and two propane tanks near a food court in the shopping mall, after a small fire broke out Wednesday. CNN, Littleton Colorado Channel 9.
