It's one thing to see some of the films and photos on the topic of non-violent "Action", I say action because what was done was far from passive in spite of appearances. All of the movement's activities required some level of training. The more dangerous the action, the more intense the training. The following video is a dramatization of a SNCC training session for those who were to sit-in at lunch counters as well as other places. The NAACP, CORE and other groups all conducted similar training sessions. Even these intense training bouts didn't always prevent injury but they did enable the protestors to maximize their efforts.
