"A gang is a group of men under the command of a leader,
bound by a compact of association, in which the plunder is divided
according to an agreed convention. If this villainy wins so many recruits
from the ranks of the demoralized that it acquires territory, establishes a base,
captures cities and subdues peoples, it then openly arrogates to itself the
title of `kingdom,’ which is conferred on it in the eyes of the world, not by the
renouncing of aggression but by the attainment of impunity."
St. Augustine in The City of God
