Tech isn't always the answer, but here we are on HN reading about a frustrating issue, a bunch of spinning wheels in a sense, and we're good at tech as a group.
I don't even know what it would look like, but currently the typical HN community response to this stuff is hyper-perceptive. From "here we go" to "here's what the article says". This alone is far too limited (we're not just here with our popcorn; we want to _do_) and it creates a pattern that can eventually shut out such news because no traction can be gained--what's the point.
IMO we can build communications environments and frameworks that empower ourselves and others to take creative action, even of the sociopolitical type. And if we can't build 'em, we can share and promote the news.
(Some of you are already doing this--thank you, please keep sharing your work)
I think maybe a better use of the public outrage of cancel-culture might be to direct that call-out energy from celebrities to police that commit manslaughter.
Next step might be getting pictures on such a website.
