Judge Dredd *is* the law. In Megacity 1, the teeming metropolitan sprawl that covers the east coast some time in the next century, there are no police and no lawyers. There are only the Judges: tall, helmet-clad men and women in black leather, firing QuickDethª ammo, riding cannon-equipped "smart" motorcycles.
Judge Dredd is beyond dour. He is one of the few people in Megacity with a job. The rest of hapless humanity tries to kill time in a world that frankly doesn't need them anymore. This nihilistic state of affairs leads to senseless body alterations, Juvie gangs, and Block wars (everyone remembers when the inhabitants of Desi Arnez block laid siege to Ethel Merman block).
In short, there is always a crime being committed somewhere. Thank God for the Judge! Break the law and he'll break you!
