Basically, some asshole named Kehoe was pissed off that he couldn't pay off his mortgage because taxes for the Bath Consolidated School were too high. So, like any reasonable person, he decided to blow it up. He spent over a year gathering explosives and wiring it inside the school right underneath the classrooms. Then on May 18, he bashed his wife's head in, then blew up his farm with all of the animals inside. As the firefighters rushed to the scene, an enormous explosion at the school killed dozens of people. Then, as if that wasn't enough, Kehoe drove his car to the school and blew it up, killing himself and a few others, including the school superintendent. And in an ironic twist, the police discovered that if he had sold all of the unused equipment on his farm, he could have easily paid off his mortgage.
This is the best example to use when an old timer tells you how kids today are so terrible shooting up schools, when the worst massacre probably occurred before he was even born!
Me: Are you fucking kidding me? You do realize that the worst school massacre happened in 1927, right? Ever heard of the Bath School disaster?
