I think you already knew about this, but the worst school violence attack was in the 1920s when an official of the school blew it up with TNT killing 44 people.No actually I didn't know about that. What I had in mind was the bombs the boys made at Columbine out of Propane Tanks, Nitro Cartridges for pellet guns and alarm clocks. Luckily most of those bombs failed due to the use of cheap alarm clocks.
