I thought that (as an example) the pioneering video recording of the Vietnam war was essentially in shaping the US American public opinion on the war matter. I could be wrong, but it wasn't seen as something horrifying back then.

It's of course the actual murder which is horrifying.

The problem isn't the documentation, but how we as a global society chooses to work with those documents.

I'm not particularly deep into the issue, but I feel there must be something between glorifying it in some engagement-metric heavy filter bubble and making it an agenda to purge whole vaguely defined categories of content from the internet.
