In 1977, an enduring character was created for the pages of the IPC comic 2000 AD: Judge Dredd, lawman of the future, the most visible symbol of police procedure – a helmeted, black-clad, motorbike-riding policeman patrolling the streets of Mega-City One, a vast metropolis stretching along the eastern coast of the US, whose remit also allows him – as his honorific implies – to be an on-the-spot judge, jury and, when the occasion demands, executioner.
