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
deadly weapons 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. An authentic buck pacifist has rarely been
seen off Earth, and it is doubtful that any have survived the trouble
there...regrettable, as they had the biggest mouths and the smallest brains of
any of the primates. The small-mouthed variety of anarchist has spread through
the Galaxy at the very wave front of the Diaspora; there is no need to protect
them. But they often shoot back.
