It is the height of moral conscience to refuse to obey an unjust law. To obey an unjust law is to give credence to its oppressive power. To obey a law that punishes where no crime exists is to surrender to tyranny and, by acquiescence, endorsing the oppression.
The only righteous place for this kind of man is the jail cell. He must break the bad law openly and without apology, and without any victim but the pride of the state, it will be soon apparent to all that an injustice has taken place. Gradually, eventually, a crisis in the public confidence occurs, and in this vacuum, in this opportunity, change will come.
