Unfortunately,

even then I could not find a
preferable solution to the threat of immediate attack than that
of counter-attack. I am aware that the state might call my
actions criminal, but how do they rationalise their own acts
of violence? Perhaps by calling them law? I teach many
strategies to evade attack; avoidance, escape, verbal
dissuasion, loopholing and posturing. But what do you do
when all of these techniques have been exhausted and you
are still facing an adversary that wants to step outside the law
and attack you? You are left with a choice, either become the
hammer or the anvil -hurt or be hurt, kill or be killed. Does
that sound brutal? Are these the words of an uneducated
nightclub thug?
