Return to Dunblane With Lorraine Kelly 9pm, ITV The 16 children murdered in the gym hall of Dunblane primary school in 1996 would be in their early 30s now. To mark the 25th anniversary of the shooting, Lorraine Kelly – who reported from the scene for GMTV – returns to the town to talk to survivors and relatives of the victims. She finds sadness but also resilience: in subsequent years, the people of Dunblane have campaigned for changes to British gun laws and offered support to those affected by school shootings in the US.
