Most protesters were moving away from the approaching police but the elderly woman and a man to her side in white stood facing the police, not wanting to move even though the police were yelling to do so.
The woman was shoved but im a place where taunts and aggressive language was used by protesters it is easy to see how an agitated policeman coud push her away.
The woman was pushed away and fell but it wasn't a tackle designed to cause her to fall to the ground.
