Here is the worst tragedy in US School history,
With all due respect and sympathy to the victims and their families of the Columbine and McDonald's shootings, the Oklahoma bombing, and other mass murders, they were not the worst mass murders of children in the US.
On May 18, 1927, 45 people, mostly children, were killed and 58 were injured when disgruntled and demented school board member Andrew Kehoe dynamited the new school building in Bath, Michigan out of revenge over his foreclosed farm due in part to the taxes required to pay for the new school.
