What are you talking about? I downloaded the video, imported it into my video editor and I went through the sequence frame by frame. The trip was accidental and it happens at every level of sports, even in Olympic running events, as Zola Budd can attest.
Getting side tracked by details and excuses BS and exactly what those that support the attacker want.
The video clearly depicts her actions and unprovoked level of brutal violence, extremely well.
I just tried to warn you...you might be stripped naked, slopped with tar, dragged through the ally's while being whipped by the old women..and then strung up by your nipples.
That's all..............
