A video of a violence incident involving two people on a LUAS has been circulating across Whats app groups and online social media sites. The video of the altercation shows shocked onlookers witnessing the violence but not intervening to try and end it. 

Leslie Shoemaker Psychologist and Lecturer in TU Dublin joined Ivan to explain what is the appeal of watching these kind of videos and why would anyone want to watch a video of this nature.
