Part of me wonders how this will affect the schools in which the suicides took place in (and, perhaps, attitudes towards the bullies).
I attended, for example, Columbine High School starting a few years after the shooting. Myself and most of my peers had lived in the town when it occurred, and knew people, friends, even siblings who were in the building, tramatized, injured or killed in the attack.
Now, a lot of the blame was placed on bullying as you probably know, and while there was some significant bullying at Columbine, I don't think Harris or Klebold were actually bullied much if at all (I've looked up a number of articles on the incident, in fact my search for better understanding left me with an oddly large knowledge of serial and spree killers but little actual understanding of most of their mindsets). In particular, Dusty Hoffschneider was well known as his elder brother Rocky Hoffschneider (yeah, Dusty and Rocky are their real names, so I guess their father was pretty on-the-nose and insistent they be 'hard') had very extreme reputations as bullies (and star jocks). People in this town did not give that family much slack or sympathy after the shootings.
And when I finally attended Columbine, that common memory, accurate or inaccurate as the role of bullying in the shooting may have been, seems to have done something. That is to say, there weren't really many bullies. Even when their were, tolerance shot straight down to zero. Compared to what I've read of other schools, it seems like cliques, while extant, co-mingled pretty pleasantly. I'm convinced that as terrible as that massacre was, this one good thing did come out of it.
Now, these suicides aren't quite so large in scale as that, but I must wonder: how is this going to affect attitudes at those schools, if only for the next few years?
