When a brutal crime is committed who is ultimately to blame – the perpetrator or their brain? Neuroscientists are generating ground breaking research that sheds light on why some people can’t stop themselves from committing harmful or criminal acts. This is creating new challenges for the justice system and making us re-evaluate the way we sentence, punish and rehabilitate people for criminal behaviour. Featuring lead scientist David Eagleman, Director of the Center for Science and Law and author of international best-selling books Incognito and The Brain, this documentary challenges our most fundamental beliefs about crime, punishment and free will.
