Dear Moish: I recently read in the Israeli press an article by Milton Konvitz on the subject of non-violence and civil protest. The introduction to the article states that it was published in an English work which is על חוק ואדם, probably "On Law and Man." The publisher I believe is the Law School of Tel Aviv University and it was published in New York. It contains amongst other things a pretty good run down of all the sources for non-violent civil protest in Judaism, and I strongly suggest you get it for your own work. Helpfully yours, as ever, Cordially yours, Norman
