Most of what gets uploaded anywhere or even worse, the stuff that goes viral, has a pretty heavy selection bias. To know whether the stuff that got shared publicly tells the whole story or a misleading story, you have to know more than just what got shared publicly.

Maybe the event that everyone pulled out their phones for had some important context beforehand, but at that point it didn't look noteworthy enough to pull out anyone's phone for. Now you'll have tons of recordings of the same event, but that doesn't mean any more context than one video.

I prefer a story written by someone who was there to a story written by someone who looked through all the thousands of posts to social media, but wasn't there.
