It isn't staged exactly: you can't fix a programme when there is a cash prize on offer, and Hunted is offering a £100,000 prize.
However most of the "powers of the state" are "replicated". Obviously Channel Four can't just ring up the police for a CCTV feed for the purpose of good telly. What this means in reality is that the camera operator with the fugitive reports to the programme researchers whenever they believe the fugitive would be on CCTV, on ANPR, or would have used the postal service, or shown up on a mobile phone cell site. The Hunters are only given this information if they've worked out they need it. But the information comes from the camera operator working with the fugitive, not from any other source.
It makes it feel very staged because, really, most of the premise of the programme is fabricated.
