Thoreau, Gandhi, and Martin Luther King all engaged in civil disobedience, and are widely admired for doing so.  But how can democratic society function if each person’s conscience has to be satisfied for a law to be obeyed?  When is civil disobedience justified?  When is it required?  How does the concept fit with the great ethical and political philosophies?  John and Ken discuss the ethics of protest and punishment with Kimberley Brownlee from the University of Manchester.
