Nowhere have the riots won any concrete improvement such as have the organized protest demonstrations. When one tries to pin down advocates of violence as to what acts would be effective, the answers are blatantly illogical. Sometimes they talk of overthrowing racist state and local governments and they talk about guerrilla warfare. They fail to see that no internal revolution has ever succeeded in overthrowing a government by violence unless the government had already lost the allegiance and effective control of its armed forces.Anyone in his right mind knows that this will not happen in the United States. Furthermore, few, if any, violent revolutions have been successful unless the violent minority had the sympathy and support of the non-resisting majority.
