There is a cameraperson 'embedded' with them - makes them kinda noticeable, don't you think! But don't get me started on this programme - it is totally unbelievable, as can be deduced from the very opening:
'For the purposes of this programme some powers of the state such as CCTV, ANPR cameras and mobile phone tracking have been replicated'
Oh yeah? Replicated how, and to what extent? Presumably the Hunters are given the information [as if[i] they had access to the above. All those lucky guesses and ground force Hunters so often nearby. And I bet you anything that it will end with one or two of those being hunted race to the helicopter/boat and just make it....
