The scores are tied, the shot is after the siren, and the video shows the player runs in a straight line to the goals. That's pretty clear. For the umpire who wasn't even the closest umpire to come in and over rule the decision to say that it's no score, has altered the result on purpose. This is the umpires first game umpiring Donald after they had complained about him previously, it's a mess.
How can you say it was clearly a decision by the ump to fix the game? What would he have to gain by making that decision? He would have known the game was being videod and that by making that decision would have come under scrutiny. To say he is a cheat is pretty strong.
