Also a lot of sources are censoring the footage, and admittedly it's pretty brutal to watch, but Wikipedia is currently hosting a copy of the an Instagram reel that caught it. I'm not recommending watching it (again, explicitly, it is very gruesome violence even considering who it is), but archivists may want to snag a copy for posterity before it gets wiped from major platforms.
