Thought it was a really good documentary and parts were disturbing to watch. Stinson clearly believes in what he's doing and I'd tend to agree with him, he seems to get some results. It was, however, baffling that the "Roger" fella wasn't charged by the CPS. Especially when you watch the video of them confronting him, he knew full well what he was doing and showed very little remorse. Apparently he's a Tory councillor which may be telling in why he wasn't charged and convicted when others were with seemingly less evidence.
Definitely worth a watch on 4OD for those who haven't seen it. It was quite shocking really that paedolphilla seems so rife in these online chat rooms and that these guys were arranging to actually meet up with people they believed to be well underage.
