As she creates all this chaos, what do you think her kid is doing? Do you think her kid is looking out for cars in the parking lot, or any other dangers a 6 year old is likely not paying much attention to while the kids mother rages on? Why are you ignoring that fact?
Why deny hyperbole when you double down on it with your attempt at equivalence?
I don't know what video you watched, or even if you watched it, but the fact she started fighting and resisting is well documented by both the video, and witnesses.
Again, I doubt the cop tried to knock her out, but I don't know that for fact, it's just an assumption, like most of what you have been saying.
