Probably deemed to be off topic according to the HN guidelines: https://news.ycombinator.com/newsguidelines.html

Although personally, it struck me as very strange that someone who's just witnessed her partner being shot (and who is currently in some need of medical treatment) that her reaction is to reach for her phone and the live streaming feature of an app. I certainly think that falls under "evidence of an interesting new phenomenon".

Edit: I don't mean "strange" in any kind of moral judgement. My heart goes out to this woman and her child who had to witness this and who've lost someone close to them. I mean strange in the sense that this isn't how I would expect someone to react.

Police brutality has been a serious problem in the US for decades, and it seems that putting a streaming video camera in everyone's pocket might help shift the narrative back in the people's favor.

Her actions demonstrated amazing presence of mind. She's probably not trained as an EMT. But she did think to document the situation. It's just very lucky that they didn't shoot her too.

It is possible that it is a victim of the HN ranking algorithm, which I believe discriminates against posts that acquire a lot of comments relative to age/votes as a way to avoid "controversial" posts.

So any thread which gets immediate traction is censored? Something seems wrong with that.

As I recall, HN algorithms cull posts that rise too fast with too many comments.
