Redmond-Bate v DPP- three Christian fundamentalists were preaching, with initial agreement from the police. A police officer on patrol later observed that a hostile crowd of 100 or more people had gathered. Fearing a breach of the peace, he asked the three women to stop preaching and, when they refused to do so, he arrested them all for breach of the peace. a police officer has no right to call upon a citizen to desist from lawful conduct unless this gives rise to a reasonable apprehension that it will, by interfering with the rights or liberties of others, provoke violence. If the speakers were being so provocative that someone in the crowd, without being wholly unreasonable, might have been moved to violence, the officer would have been entitled to arrest, if they refused. freedom of speech includes 'not only the inoffensive but also the irritating, the contentious, the eccentric, the heretical, the unwelcome and the provocative, providing it does not tend to provoke violence.'
