A woman defies police orders to back up and asks them what they're going to do about it.
It's like people forgot actions have consequences. Never in my life, even if I were a 110 lb woman, challenge dozens of cops to do something about it. Then the crowd is shocked when she gets arrested? Did no one teach any of these people how laws work?
I don't care if you're out there protesting. Good for you, but be respectful and follow the order of the law. To think you have some invisible shield around you and you are immune to consequences is madness.
