Those who refuse to support and defend the state have no claim to protection by that state. Killing an anarchist or a pacifist should not be considered "murder" in a legalistic sense. The offense against the state, if any, should be "Using deadly weapons within city limits," or "Creating a traffic hazard," or other misdemeanor.
