Newspaper sales are declining but editors know there's one topic that will keep on selling: crime.

We're fed a diet of gory details about criminals and their victims, which evidence shows is clearly popular.

But why does crime sell?

Our panel today:

• Nicola Tallant, NNI crime journalist of the year and Investigations Editor of the Sunday World
• Dr Mark O'Brien, lecturer in crime in the media and chair of the Communications Studies degree at DCU
• Mary Aiken, cyber-pyschologist and director of the Cyber-psychology Research Centre at the RCSI
