In the NY Times interview with Bill Ayers that came out by coincidence on 9/11/2001, Bill Ayers explains that he has no regrets for the bombings that the Weather Underground committed in the 1970s as he views them as innocent in comparison to US bombings in Southeast Asia.  Weather underground members have argued that those killed in their bombings were police and in their eyes combatants, not civilians.  Do you believe that the weather underground should be considered a terrorist group or a criminal group?
