In this show he conducts Psychological Autopsies on the mass killers responsible for the Hungerford & Dunblane shootings and the infamous Rothbury manhunt, along with cases including the Heinz baby food poisoner, the Tesco bomber, and numerous attacks by ‘deranged’ spree killers. Some ‘forgotten’ mass killer cases and other ‘near-misses’ are used, and audiences will be struck by how close many would-be mass killers come to executing their deadly attacks. Professor Jackson reveals that despite the UK’s tough firearms laws, mass killers are very unpredictable and often almost impossible to stop, and he looks at what can be done to make sure future mass murders are prevented.
