I saw that - a YouTube vid - a few days ago. My impression was, frankly, that it could have been - at least partially - staged. Partially: maybe the mob - the aggressive ones, and the bystanders - were real-life, but the situation itself might have been "constructed" (="provoked"), with the harassed lady and the camera-guy (gal? zey?) being central in this, plus maybe a part of the bystanders too. And hypothetical "worst case": all, even the attackers, staged.
Why that impression? :
1. can't believe that in "real life", over the couple of minutes, the lady pushed and lying on the ground, no-one (literally no-one) tries to approach her - see if she is conscious/injured, or speak to her, or soothe her, try to get her up. Yet that's what the vid (no breaks there) shows: not a single one comes to help.
2. the vid I saw (maybe it was the "original", later multiplied ; that "original" seems vanished on YT), it had a longish description, seemingly written by the camera guy/gal/zey. Just scanned it - there was a, somewhat urging, motif there: the lady was kinda "nearly-identified", and the motif, twice or thrice repeated, was kinda "c'mon, folks, let's collect some dough for her via GoFundMe".
Looked good-hearted, but my gut feeling - mho - tended towards "hmm...".
And - but that's for police/investigators - find the involved people / find other takes (smart phones are these days everywhere) / draw conclusions about the nature - fake or real ? - of all this.
And if fake :
1. a scam, trying to milk the GoFundMe cow?
2. psy-op of Trumpsters (organized individually / by local T-support (/ unlikely, by T-campaign))?
(while there, of course, is no doubt that goons criminally, and in "masses" (samples: San Jose, El Cajon), attack Trumpsters ; all that on the "wings" of BLM- and SEIU-thuggery, and progressively puppeteered by Glorious Heroes of The People in the mold of Comrades Creamer/Foval/...)
