While school mass murders seem to be more frequent now, it's not a new occurrence. The worst US school mass murder was in
1927! http://listverse.com/2008/01/01/top-10-worst-school-massacres/ Bath School disaster
45 died | 58 injured | Andrew Kehoe
May 18, 1927 : In the deadliest mass school murder in United States history, former school board member Andrew Kehoe set off three bombs in Bath Township, Michigan killing 45 people and wounding 58. Kehoe killed himself and the superintendent by blowing up his own vehicle.
There have been many others over the years, but there are more people now and the notoriety given to the perpetrators in the media seems to have pushed some of the killers over the edge.
Personally, I think many of them get the idea from previous events and would never have thought to do these atrocious acts on their own.
