So she went to her knees after a balloon popped in her face. An exaggerated response, but nothing as egregious as OP implied
I had a feeling that the audio was embellished. Pretty funny that it was faked. Still funny that she went down to the ground. Watching it closer, the officer's finger never gets close to her eye.
It's possible that the balloon had been doused in Pepper spray, brushed her eye, and that was the cause for the protestor's discomfort, but I don't know because I don't get my info from fake 10 second viral clips that I find on Twitter
Something clearly hit her eye. That's the sort of response you have when you lose a contact lens. It may not be well known by some of the people in this thread but the eyes are rather sensitive. As an adequate demonstration to those of you that don't understand this, go grab some hot sauce from your kitchen and squirt it directly into your eye. Post your results to this thread as soon as you're able.
That is an extreme response. It's okay to call that protester a sensitive, delicate flower. She probably cries from a paper cut.
Seems to me you watched the fake video and not the real one posted on the 1st page of the thread. <iframe width="560" height="315" src="https://www.youtube.com/embed/AS8X2Qp_6aA" frameborder="0" allowfullscreen></iframe>
