It's a livestream of a racist gunman shooting actual people, together with his commentary. Real people are really being killed in that video. I'm not a fan of censorship, but this shouldn't be publicly available.

Well, it's just a video now. It was a live stream. It's awful what happened, but it's just footage documenting the event now. I understand why you wouldn't want it hosted on something like Facebook or Instagram or whatever, but to say it shouldn't be out there somewhere? What if someone wants to analyze the event, most big events don't have near that level of documentation. How is it different at this point (just the video of the event, not the event itself) from journalists documenting other awful things?
