The terrifying CCTV image of a toddler being led to his death haunts this episode of Law & Order UK which deals with the difficult and morally complex issue of children who kill. As a society, we are very unforgiving of child killers but if the killers themselves are only children, it begs the question - who really is responsible for the crime?

In an emotionally gut wrenching episode, George defies his superiors and instead takes instruction from the victim's mother who has a surprising point of view on the crime. Can the justice system, and ultimately the government, afford to be lenient?
