We did carry out symbolic acts of extreme vandalism directed at monuments to war and racism, and the attacks on property, never on people, were meant to respect human life and convey outrage and determination to end the Vietnam war ... The responsibility for the risks we posed to others in some of our most extreme actions in those underground years never leaves my thoughts for long. The antiwar movement in all its commitment, all its sacrifice and determination, could not stop the violence unleashed against Vietnam.
