Those who refuse to support and defend a state have no claim to protection by that state. Killing an anarchist or a pacifist should not be defined as "murder" in a legalistic sense. The offense against the state, if any, should be "Using a deadly weapon inside city limits," or "Creating a traffic hazard," or "Endangering bystanders," or other misdemeanor. However, the state may reasonably place a closed season on these exotic asocial animals whenever they are in danger of becoming extinct.
