Mr. russell: I'm 75 and, while a young man in So. California marched in Civil Rights Movement events.  We were "trained" prior to those events in "non-violence" and were dedicated to such non-violence.  IMO, today's counter-protesters need the same training....it's not easy to stay "non-violent" when someone spits on you.....and the same dedication.  Additionally, those who are dedicated need to support non-violence by promoting it among fellow protesters who might be more inclined to violence.  As tough as it might be, that mkight include stepping in front of violence-prone individuals to keep them from become violent with others.......no one said it was going to be easy.  Gary Crum
