famous schoolyard killings (the one in Paducah comes to mind) it was commented in several places that school shootings occur several times a year, but almost never make national news.
I just checked Wikipedia for school shootings. Here's a link to the article:
http://en.wikipedia.org/wiki/School_shootingThe day of the spree killing in Illinois, one news report (on NPR probably) mentioned that this was the fifth such shooting in two or three weeks -- can't recall the exact number of shootings nor the number of weeks. But I had not heard of any of the others. Neither, apparently, had anyone else I mentioned that to. Now that I scroll down through the linked article, I kind find the other ones:
Notre Dame Elementary shooting Portsmouth, Ohio, United States February 7, 2008
Louisiana Technical College shooting Baton Rouge, Louisiana, United States February 8, 2008
Mitchell High School shooting Memphis, Tennessee, United States February 11, 2008
E.O. Green School shooting Oxnard, California, United States February 12, 2008
Northern Illinois University shooting DeKalb, Illinois, United States February 14, 2008
There's no Wiki article for the Notre Dame Shooting. But more searching reveals that a man shot his estranged wife in her classroom, then eventually killed himself. In Louisiana, a woman fatally shot two students then killed herself. In Memphis a student critically wounded another student.
Notice that was four previous shootings in one week. Om Oxnard, California, an 8th grader killed another student, apparently because the second student was gay.
Because not too many people were killed, those earlier shootings simply didn't make national news. And if you look at the entire list at the Wikipedia article, I think you'll be surprised at how often such things have happened over the years. Then click on the link to other notable school shootings, and you'll be shocked at how many there are. I stand by my point that these things (sadly) happen all the time.
