VaTech massacre

There's little I can add to the discussion that hasn't already been said. Of course it's tragic, of course the media is grasping for explanations and some way to fix it so another tragedy can be prevented. ll I have are some random observations:

• Was it just me, or did the early news seem to harp on the fact that the shooter was a Korean national? Technically it's correct that he wasn't born here or a naturalized citizen, but having lived here since childhood I imagine he was certainly "Americanized" - it just seems to me that racist idjits will jump on his nationality as part of a larger "damned furriners" argument.
  
• Both sides of the gun control issue seem eager to use this as an argument for their respective positions - I'm not wading into that one because IMHO like it or not, guns are so taken for granted in American culture that both sides seem to miss the larger point, which is: what motivates someone to go on a killing spree anyway? Is it individual, societal, some combination, something else? Why is it almost always schools getting shot up? Why are the shooters almost always young men?
  
• Is there really any way to see someone going down that path, and do anything effective? FWIW, I do think Cho's teachers did just about everything they could legally - one blogger discusses their own experience helping someone on the edge and points out that to someone in this frame of mind, normal deterrents are useless.
  
• Police response: I'm no expert in crisis intervention, but I'm not sure how practical it would be to try and lock down a campus of ~30,000 students + staff, most/all of whom are legal adults and as such their freedom of movement can't be squashed the way it might be in a K-12 (underage) environment.
  

I can't add much else.
