'Paedophile Hunters': vigilantes who attempt to lure and confront suspected sex offenders, before calling the police in an attempt to entrap them and have them arrested. But are these self-appointed groups a help or hindrance to the authorities? Do their stunts lead to more sex offenders being convicted? Or do they just waste police time? Andy & Neil explain how this phenomenon has grown over the last few years, and whether 'Paedophile Hunters' are a problem for police, or part of a solution.

Later, Neil explains whether members of the public would be wise to attempt a citizens' arrest on a police officer if they suspect the officer is committing a crime, and Andy reveals what happens if a prisoner who's already serving time for a serious offence kills a fellow prisoner.

Plus, Andy & Neil look at the role social media played in radicalising the Southport attacker, and whether this strengthens the case for banning children from using social media.
