The woman with the camera has serious bullying issues. Who's supposed to be the privileged one again?
I kinda get where you are coming from. The white woman is obviously having a mental breakdown. But, the black woman knows that when the police get involved, POC are usually the ones who get the consequences (like death). So, I don't blame her for filming the entire incident. The white woman constantly says on the phone with the police the black woman is threatening her.
In situations like this, I'd love to see the five minutes before the camera started to roll to really know what the hell happened. In the version I saw, the white woman tried to hit the black girl, then collapsed on the floor...
