A week before Christmas, how tragic
I'd be interested to know if you could generalize rampages like this to suicide. I know that in Ireland, they don't mention when someone killed themselves due to the possibility of copy-cat suicides. In the media they say that the person died due to tragic circumstances. http://en.wikipedia.org/wiki/Copycat_suicide
I'd love to know the probability of two rampages occuring during the same week in areas that aren't normally at a higher risk of gun violence (googling Newtown seems to make it seem like any normal middle class town).
