Disinterested party, actually.
I was spectating roughly 200 meters from the finish. There was absolutely no battle until the very end which you can CLEARLY SEE IN THE VIDEO. I assumed it was the over-reaction of a race official until this video surfaced. Now, having watched it carefully multiple times I have come to my conclusion.
The Saugus runner clearly had the intent of cutting Barr off. If that were not the case, she could have run to the left of Barr where she would have avoided the ladder. Dirty running on her part.
As far as your own race experience and being cut off? Irrelevant. Does Barr shift to the right (or left for that matter) at all? No. Does the Saugus girl quickly cut left right before Barr goes down? Yes.
It seems as though a combination of a race official proving his/her worth by making such an important call and the Saugus girl lacking confidence in the rest of her team thus sacrificing the integrity of her own race has resulted in Barr becoming the scapegoat for one of the biggest upsets in high school cross country.
Its a shame so many of you feel so invested in this event that you cannot throw away your bias and see the reality of what happened. Whichever official made the call must be regretting the decision now that the video shows just what happened.
