Well, addressing real problems is to much like thinking.

I'd recommend reading Mark Ames Going Postal, I just returned it to the public library today. He discusses school and work place shootings and the social blindness as to the actual cause.
To show where's he's coming from, his thesis is that modern shootings are rooted in 18th and 19th century slave revolts in the America's - the reactions of people at the time are startlingly familiar in their language.
