If you are neutral in situations of injustice, you have chosen the side of the oppressor. If an elephant has its foot on the tail of a mouse and you say that you are neutral, the mouse will not appreciate your neutrality.
We must not allow ourselves to become like the system we oppose. We cannot afford to use methods of which we will be ashamed when we look back, when we say, '...we shouldn't have done that.' We must remember, my friends, that we have been given a wonderful cause. The cause of freedom! And you and I must be those who will walk with heads held high. We will say, 'We used methods that can stand the harsh scrutiny of history.'
