He's a Met Police detective and hs job invoves monitoring chat-rooms etc.
The police moinitor chat rooms and trace men (usually, though not exclusively, some women 'procure') arranging 'meet-ups' with children.
He caouldn't discuss too much of the detail, but I am so proud of the job that he is doing. There can be no entrapment. Paedophiles are given enough rope to hang themselves and then busted when they try to meet up with who they think to be a child.
What I found really distressing is what these people buy, or are found to possess, on their way to meeting 'the child' to enable them to act out their sexual desires.
