Update:
As with most things that comes from the anarchist protesters, this too was a lie:

Here’s the video of the horrible event of the car that “plowed through them” and “knocked down one of our protesters”. Notice how not only do they try to stop the car, which is moving slowly, but no one is actually hit, no one appears to have been knocked down or hurt. On the contrary, if you watch it slowly, you can see them rushing at the car from the sidewalk. No wonder the driver sped up to get away. But they’re still screaming about how the horrible police ignored this injustice.

*By the way, Julie Bush, one of the folks propagating this lie, has written fiction for Sons of Anarchy. How appropriate…

**Prior to this horrific incident, these lovely young folks were burning an American flag.
