You might want to do a wiki search of Andrew Kehoe before declaring that there were no school massacres. The worst in US history was in 1927.
People have no interest in anything that might suggest that the US wasn't a perfect paradise until 1960.
Indeed, and if I’m not mistaken the Bath School Massacre still stands as the worst school-related mass murder in U.S. history.
Somehow, I don’t think reading the funny pages caused Mr. Kehoe to blow up a school full of kids.
The only paper that set him off was that property tax bill.
