First of all, this was INCREDIBLY obvious. I am not a track official, and without reading a word of this before watching, I spotted lane 3 jumping, in the real-speed video, while eating lunch at my desk.
Secondly, this seems to be a thing for Schippers. Does anyone remember a recent Diamond League race where she false started, then ran under protest and won off of the second start?
They ended up giving her the win, even through her false start was FLAGRANT. The very knowledgeable TV commentators (CBC in Canada) were amazed. They felt that any runner other than her (she was the meet's main attraction, in the final race) would have be DQd and sat out of the second start.
