Actually, using the Daleks would be a masterstroke. Everyone loves Doctor Who - who wouldn't be thrilled by the sight of a real-life Dalek squadron rolling down the high street, glinting in the sun? The sheer excitement would genuinely make the accompanying loss of liberty seem worthwhile. To liven things up even more, our rasping pepperpot overlords would be colour-coded. Blue Daleks would deal with minor infractions, and would spend most of their time issuing warnings and administering minor shocks - but they'd also be chummy and approachable, and willing to pose for photographs with your nephew. Red Daleks, on the other hand, would be emotionless killing machines. Imagine the atmosphere outside a pub on a hot summer's day: a Red Dalek trundles past, and the convivial hubbub suddenly fades to a whisper. Everyone stiffens. And then he turns the corner and a communal sigh of relief goes up, and the drinking continues and the jukebox plays louder and louder... community spirit lives again. Admit it: it'd be fantastic.
