Okay, that wasn't the actual title but after watching it I was like what happened? It is being deemed the most dramatic/controversial moment of the 2012 Olympics so far. Basically, between the referrees, the judges, and the time keeper, someone messed up. Shin (KOR) and Heidemann (GER) had less than 1 second on the clock and it kept resetting back from 0 to 1, keeping the action going. If you watch the video, it's very confusing.
Basically, the last time the clock goes to 0 ending the match and mysteriously sets itself back to 1 after the match ended and the winning score from Heidemann shouldn't have counted.
Shin stayed on the piste (the floor) in protest while judges decided.
Fencing buffs also say the referee did a bad job of controlling the starting action as Heidemann was edging up closer (Shin literally had her back up against 'the wall' by the time it was down to 1 second) and started her last action before 'start' was called.
With the Olympic staging and lighting, it made for some dramatic photos. The spectators also seemed to be on Shin's side and not on the officials.
