If we're gonna follow the guidelines, then the Boston bombing was entirely off-topic and should have been removed immediately instead of getting thousands of points. The only Boston-related on-topic story was Bruce Schneier's view on it, which is also the reason why the other stories should
not have been on HN.
> Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. [...] If they'd cover it on TV news, it's probably off-topic.
Edit: Well that was a quick downvote. Guess the Boston bombing strikes a nerve. But is it so hard to be objective about it?
