A Field Guide to Monkeywrenching

If a stranger batters your door down with an axe, threatens your family and
yourself with deadly weapons, and proceeds to loot your home of whatever he
wants, he is committing what is universally recognized-by law and morality as
a crime. In such a situation the householder has both the right and the obligation
to defend himself, his family, and his property by whatever means are
necessary. This right and this obligation is universally recognized, justified and
even praised by all civilized human communities. Self-defense against attack
is one of the basic laws not only of human society but of life itself, not only of
human life but of all life.
