@Whenthesunshines - The auburn haired girl was sitting quietly on the band stand, holding a made sign about not feeling safe.
She sat with three friends with her back against the pole, and tried to stay there while police were swarming around pulling at her and her friends. She looked scared more than anything and was looking ahead and trying to ignore the large male officer who had his hand on her arm and was shouting in her ear and ordering her to leave.
That photo must have been taken after they grabbed her and dragged her back.
There is a full feed on YouTube if you want to watch. You can see it was peaceful at the beginning, what happened when the police rocked up, and you will see it is calm and peaceful again now that the police have gone.
