It's most certainly behavioral. I can look at the George Floyd case and say, "Here's an instance where whipping out your camera phone is beneficial" but the vast majority of cases are people just trying to embarrass each other via the metaphorical internet army. 4chan, when I was a kid, had a saying that went "not your personal army" that was organic from what I could tell and for precisely this purpose. I don't think you'll get that level of awareness out of post-2007 internet denizens.
