He didn't "film most", there were many other streamers, besides just journalists, and the countless people going on with their phones in hand (filming other people going around with their phones in hand), and security cameras, and so on. He wasn't even the only to film death of Ashli (not "Ashley"), there were many others who also did.

And I don't he filmed what he posted here. Or that he even ever left America.

Yeah, I checked his timeline. He just reposts Ukrainian videos.
