Rating: Rating: When a ‘riot squad van’ turns up at the home of a schoolgirl to make sure she’s obeying Covid quarantine regulations, you can’t help wondering what the police would do if they ever discovered a real crime. Taken: Hunting The Sex Traffickers (C4) supplied the answer. There will be a whole lot of serious surveillance. The gangsters might not have their collars felt, but they’ll certainly appear in many long-range, fuzzy photos. Villains beware. If the family of 12-year-old Charlotte Crook in Manchester were watching, they must feel more bemused then ever. Their daughter was visited twice as she isolated last week by coppers who turned up in a van with an armoured grille over the windscreen. Perhaps they thought she might open fire with a water pistol.
