What about the bloke who turned state? My recollection was that his touting wasn't enough to avoid being charged, or have I misremembered that? As for the state surveillance, whilst the CCTV may have been of some importance in securing convictions, it's equally the case that the participants' blyth disregard of the likelihood (certainty, in fact, if anyone had bothered to do their homework) of the station being camerad-up was what allowed the footage to be used in the first place. That degree of amateurism was something that was far from new to a couple of the participants - a fact which, whilst it might not have led to their getting lifted the first time around, may well have been a factor in their being on the radar in this instance....
