As a Quaker, I have to give a shout-out to the awesome Alternatives to Violence Project. This guy used what AVP calls "transforming power."
From this website: http://www.washingtonpeacecenter.org/articles/prisonnonviolence.html

"Transforming Power...has to do with an individual drawing upon his or her inner resources to act powerfully to change negative situations into positive outcomes. AVP encourages people to cultivate their faculties of reason, faith, language, creativity, intuition, humor, courage, patience, discipline, and attitude. Transforming Power is about using these faculties to take an active leadership role in resolving conflict. It requires that one be simultaneously aware of the feelings and reactions in oneself and in others, understand the tensions present in a conflict, recognize the various options available, and act decisively to create solutions that avoid or reconcile violence and injustice."

This vehicle was also featured on an episode of Teletubbies -- it's one of the random videos they watch on one of their tummy-screens. If you happen to catch the correct episode on TV, you get to watch the slowly-paced, minimally-narrated short documentary "again! again!"
