The justice is system exists to preserve itself. If all criminals were punished, if every innocent was freed, there would be no need for law courts, bar associations, law reviews, law schools, law makers, police, private investigators, blackmail networks, penitentiaries and private jails.
The whole system is a con, as if the rotten hull of an old clipper ship so worm eaten that only the calcium secretion which lines the worm holes keeps the old analogy afloat.
We'd need a Second Coming of Christ to dispense with our current corrupt system of justice. It is the inner, not the outer, being or form, transformed by conscious connection to timeless hyper reality of a self aware universe.
