Referees, judges & umpires

I can't stand referees, judges & umpires. They seem to make the worst decisions when the game is the most important & the decision they make can change who wins or loses. Case in point, The San Diego/Broncos game last week. The play with less than 2 minutes left in the game, when The broncos quarterback fumbled the ball & San Diego got the ball, would have guaranteed a San Diego victory but the referee called it an incomplete pass, reviewd the call & admitted his mistake but still gave the ball to Denver. They went on to score a touch down & won the game. In real life if an employee makes a decision that costs the company money or makes the company go out of business, they are fired. Why couldn't the referee, say "my bad" & do the right thing?
Judging for gymnastics, diving, bull riding & any other sport that is judged for style is lame. I have watched olympic athletes do some amazing things but because the judge has problems with that athlete, they get low scores while loser athletes that kiss up or are liked by the judges, get high scores. This is wrong & needs to be changed. It is hard enough in life to become great at anything but to become the best & have everyone know it & then have some want a be judge give a low score because of their own small guy syndrome, is wrong.
How can you have 9 judges give a high score while one judge give the lowest score on the same performance, this is crazy. I think that when judges, umpires & referees make poor calls, we the fans or athletes should be able to throw up signs from 1-10 & rate them & that way if they get high scores, they can keep their job, if they get low scores, they are fired.
