NBC did show it. Where did you get the idea they didn't?
Also, dude had every right to be pissed. If you saw the outcome and the actual body positioning at the time of the match being called it was complete bullshit. Cost him the gold medal IMO.
NBC even showed how he went up to the judges and complained and asked for an instant replay and they laughed directly in his face.
What he should have done was toss that medal in their faces and then whupped their asses. He was clearly the better man that day. You don't reward first class performance with a third place trophy after a bullshit call.
