In 1968 as a young adult I went to 2 different protests against the Vietnam War. I went from Boston to D.C. by airplane, had an arranged place to stay with other young people in a nice home in VA. The protest march organizers fed us and talked about what we needed to know when marching with  thousands of other protestors. They bussed us to D.C. close to the Pentagon. I got to march in the vey front line. The police started to round up the peaceful protestors in the front line. They got me and were going to put me in a police van but the 12 seats were full and I was number 13, which I joke is still my lucky number. I had a cause with millions of other American's and the war was so unpopular that it ended. The young men in my family were in Vietnam. I spent my marriage in a military family but Vietnam was a horrible war. So having "organized" by groups of recruited "protestors" for the cause is not something new, and it does work.
