Do you support what self-proclaimed 'paedophile hunters' do or should it be left to the police?

The NSPCC reported recently that the numbers of people recorded as being in possession of child abuse images has gone up by 70% percent in NI in the last year alone. There are a group of English people who say they are doing some of the police's work for them. They are posing online as children to smoke the paedophiles out...and then they confront them. On the TV show last night Stephen spoke to Scott and Callum - not their real names. They came to Belfast to explain to him why they spend their time hunting paedophiles. So what do you think - should so called 'vigilantes' be doing the police's job for them? Jim Gamble and journalist Andrea McVeigh discuss.
