> Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.
See also the very clear guidance in the welcome guidelines:
> A crap link is one that's only superficially interesting. Stories on HN don't have to be about hacking, because good hackers aren't only interested in hacking, but they do have to be deeply interesting.
> What does "deeply interesting" mean? It means stuff that teaches you about the world. A story about a robbery, for example, would probably not be deeply interesting. But if this robbery was a sign of some bigger, underlying trend, then perhaps it could be.
> The worst thing to post or upvote is something that's intensely but shallowly interesting. Gossip about famous people, funny or cute pictures or videos, partisan political articles, etc. If you let that sort of thing onto a news site, it will push aside the deeply interesting stuff, which tends to be quieter.
What's the point of posting "police should not murder citizens" posts? Anyone who isn't a vile human being agrees; and those posts always drag out the vile human beings who will blame the minor criminal who gets murdered by police.
There is no constructive discussion to be had from them. See also discussions about Israel / Palestine; abortion; gun control; etc.
Having said all that I didn't see the link and if you feel it was unfairly flagged you should email hn and ask them to tweak it. I think they do un-flag-kill some stories that they think should be here and I know of at least one that was about diversity stuff.
