Did the rate of school shootings change after the Columbine massacre was all over the news everywhere in the U.S.? I agree that the chances of any given school having a mass shooting are approximately zero, but I’m less inclined to trust an average that starts in the 1970s than one that starts in the 1990s even though more data is usually better.
(Also, should we distinguish between rampage killings in which the goal is indiscriminate slaughter and murders of specific individuals for more conventional motives that happen to have occured in a school and used a gun?)
