WATCH: Nicola Bardon talks paedophile hunters

Pat Kenny discusses Nicola Bardon's experience working with Dark Justice, a UK-based paedophile hunter group.  

The Sun reporter Nicola Bardon set up a decoy profile pretending to be a 13-year-old girl in Ireland on a teen forum to see what would happen. The response was worse than she imagined. 

Pat Kenny discusses the experience with her and how these vigilante paedophile hunters are potentially saving children from online groomers.
