It looks to me more like flag-holding-man throws it away to help someone get up, who then joins the protestors. The police officer in the yellow vest is under the arch on the right on the start, away from where the protestors are doing whatever they are doing. When a bloke in black gets up off the ground he joins the protestors too.
I don't think that is a video of protestors beating a policeman. If they were the video would probably have been more violent. I think the protestors might be helping the bloke in the blue jacket stand up at the start.
The intent of the mob is entirely comparable, at any rate. Protestors hurling stuff at police vs. protestors igniting stuff.
But that, at best, upgrades the scene from a mostly peaceful protest torching vehicles to a violent clash with the police officer. Violent protests are not unheard of. It doesn't justify the idea that anyone was trying to irreversibly stain American history with the blood of the 2nd, 3rd, and 4th in the chain of command of the United states of America.
I mean, the fundamental argument here is that we shouldn't mix the actions of the people on the stairwell facing the police with the rest of the protest. That line of thinking applied to protests was roundly debunked in 2020.
>PS. Also your video is a bit indistinct, I'm not sure it does show them beating a police officer who is on the ground
You can see them drag someone down the stairs in the first few seconds of the video and then you see them beating someone on the ground. One man is literally beating an officer with an American flag if you are one for symbolism. The next tweet in that thread shows a photo from above in which you can see the officer down on the steps and there is a reply that has video from a different angle.
