Thirty years on, the Dunblane massacre remains almost unbelievable and the grief of the families unfathomable. In a terrible way, it is almost harder to see them now, three decades on; three decades lived without the children who should now be grown up, with families of their own.
On 13 March 1996, a man called Thomas Hamilton shot dead 15 primary schoolchildren aged between five and six and their teacher Gwen Mayor in their gym as they were beginning a PE lesson. Some of them he shot at point-blank range when they were incapacitated by earlier bullets. A 16th child died on the way to hospital.
